Remove buildThread() call from mod_deletefile because deleteFile()
already calls it.
Add image_reject_repost_in_thread option
Don't do anything if a mod link is middle-clicked.

This lets Chrome users open mod actions in a new tab by middle-clicking,
as Chrome still calls the onclick event when middle-clicking unlike
Firefox.
Global missing from mod_logout
Fix incorrect log message when bumplocking and stickying threads.
Handle posts without filenames.

If a post doesn't have a filename (such as because of a post event
changing it), then don't show an empty filename with the post.
Removed redundant code in image processing.

Both paths of the code here did the same thing.
Extend timelimit when rebuilding from mod interface.

The rebuild_timelimit config option was not used anywhere since the mod
interface rewrite.
Made deleting posts by IP more efficient.

No longer rebuilds same thread multiple times.
Insert into posts table using named columns.

Makes it easier to update the posts table schema.
Fix transforming links to mod links in OP posts.

Similar regexes are called for threads and posts, but they differed
needlessly, and the thread regex would drop anything between the `<a`
and `href="` parts. This makes them both the same and functional.
Incorrect parameter type.

The parameter was bound with the wrong type. I guess the type isn't
enforced judging by how the code still seemed to work, but it probably
should be fixed.
