This runs `go fmt` on changed files and moves around some blank lines.

Move flag parsing to main.go as per the issue description

This solves the error 500 on the /api/me endpoint.

Replace token search query `=` with `LIKE` to fix sqlite complaining about
no valid tokens. Also checked with MySQL and it still works after the change.

Use the split argument list (slice) just for validation purposes
as it's substantially easier to do `.contains` in a string instead
of a slice. As such, pass the `configSections` arguments to
`Configure()` and check the existence of each one before showing
the options to the user.

An empty argument list is replaced by "server db app" so everything
is there negating the need to check anything else in `Configure()`.
In the same vein the default is "server db app".

The parsing is done in `app.go` alongside the other flags instead
of `main.go` as described in T657.

Add --sections flag to app.go according to T657, parse them
into a string array (check for invalid arguments and abort)
and pass them to Configure(). For now Configure() doesn't do
anything with them yet.

Closes T651

Update script

Closes T555

store version output in new variable
slice output indexed from beginning instead of end. allowing for custom
build version numbers.

also fix weird spacing from tabs being two spaces wide, sorry :)

And fix a typo

Ref T555

Decouple writefreely library from executable

Ref T613

This moves `hostName` to the `Collection` struct, where it's needed. The
field is populated after successful `GetCollection...()` calls.

This isn't the cleanest way to do things, but it accomplishes the goal.
Eventually, we should accept the AppCfg to `GetCollection...()` calls,
or make them `App` methods, instead of `datastore` methods.

Ref T613

(or `writefreely -v` otherwise doesn't output anything)

Ref T555

basic error check with descriptive output in update_server.sh

this bash script will download a new version, if any, and exrtact it to
a temporary location. Then copy the new files to the current directory
and restart the systemd service.

This ensures outside application builds will succeed when including the
writefreely pkg.

Ref T613

- Adds a new interface, Apper, that enables loading and persisting
  instance-level data in new ways
- Converts some initialization funcs to methods
- Exports funcs and methods needed for intialization
- In general, moves a ton of stuff around

Overall, this should maintain all existing functionality, but with the
ability to now better manage a WF instance.

Ref T613

This ensures the writefreely pkg can be used in other applications that
need to load mysql themselves -- this can be done by building with the
tag: wflib

Ref T613

(instead of writing out the logic of that helper function)

Ref T613

Ref T613

This adds a new `landing` value in the [app] section of config.ini.
If non-empty, unauthenticated users on multi-user instances will be
redirected to the path given there.

This closes T574

This solves the error 500 on the /api/me endpoint.

Replace token search query `=` with `LIKE` to fix sqlite complaining about
no valid tokens. Also checked with MySQL and it still works after the change.

change delete post authentication logic

this reorders the logic for checking authentication on post deletes to
first check for a provided edit token and after check for an access
token or auth'd user.

support pubgate

Enable un-setting RTL setting via web

Make post body h2's smaller on index pages

This adds a small margin around a time element, which makes things look
better when the body of a post starts with a header.

Previously, <h2>s in a post were the exact same size as post titles on
index pages (blog index, tag listing). This fixes that by reducing the
font-size of body h2's. Closes #82.

Include post title in zip export txt files

Modify GetPost() to allow inclusion of pinned posts

this moves the unmarshaling of a remote actor out into a new helper which
accounts for the possibility of a context being a list or a single entity.
i.e. a string or an object.

basics tests are provided for both situations

also go fmt'd the file activitypub.go

Add go-bindata as a module dependency

Previously, once RTL was enabled on a post, you couldn't unset it via
the web application. This fixes that. (Fixes #103)
