This was still a relic of Write.as. Now it has the same icon as the
WriteFreely editor.

Customize landing page

Resolves T565

Previously, we just included the value of `ul`, which is a func. This
now calls `ul()` and logs that value.

Shorter config process

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

Closes #132

This makes the naming scheme more consistent with other funcs.

Ref T565

This enables admins to customize their landing / home page via the Admin
dashboard -- including the text at the top of the page and the section
below it. It keeps the current default text, falling back to it if the
user hasn't overwritten it.

Ref T565

This supports admins previewing changes to the landing page.

Fixes issue 125

Fix #124 according to the snippet by @mrvdb

do anything useful (see https://github.com/writeas/writefreely/pull/128#issuecomment-506207107)

Previously, this would only run when configuring an instance for
single-user usage. Now it'll also run when configuring for multi-user
usage.

It also adds a log when the database has already been initialized.

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.

Always initialize database after --config

Half-fix of #96

because this is the alias in highlight itself.

(see https://github.com/writeas/writefreely/pull/128#issuecomment-505766645)

I changed the sh alias to shell instead of bash.

The additions to the `highlight(nodes)` function look redundant.
It works for me without them but maybe they cover an edge case I
cannot think about?

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.

This fixes places, especially around federation, where the Collection's
`hostName` wasn't set.

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.

Previously, this would only run when configuring an instance for
single-user usage. Now it'll also run when configuring for multi-user
usage.

It also adds a log when the database has already been initialized.

Previously, that func was duplicated here.

This verifies that a user is authenticated before getting to the actual
handler on API endpoints where a user is reading content.

Ref T576

This is the start of all changes needed to support entirely private
instances, where all blogs are only visible to other authenticated users
on an instance (ref T576). It begins by changing how Handler methods check an
endpoint's permissions.

- Renames UserLevelLEVEL consts to UserLevelLEVELType
- Adds UserLevelLEVEL funcs with same names as previous consts. Each
  returns a UserLevel
- Adds a new UserLevelReader that restricts access based on app
  configuration. This is now used on collections and posts.
- Changes routing a bit so static files are always accessible

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 :)
