Stop ignoring *.png files.

There are only a few png files in the project and they're part of the
website. So don't ignore them!
Added three icons (browse, cancel and play).
Ignore all files in the protected/runtime folder.

Also removed any existing log- and state files in that folder (they
shouldn't be in the repo).
Removed the coponents/backup folder.

It doesn't contain code that's in use, only temporary backups (from some
merge in the pre-git subversion repo).
Added reference to gradtest.js in Page.php

The gradtest.js script is not part of the repo, but the production
version of Page.php contains a reference to it.
Normalized line endings in index.iis5.php
Simplified actionGetMeta() in VideoMetaController.

Just use $_REQUEST instead of checking for availability in either $_POST
or $_GET.
Mystery commit. Whitespace troubles?

Git tells me there are changes in these files, but I can't see them. And
I can't switch branches without committing them, so here goes. BTW.
discarding changes doesn't work either. The files simply appear in the
uncommitted changes list again.
Merge branch 'normalize-line-endings' into dev

Contains only one last commit (in index.iis5.php).
Merge branch 'sync-with-production-website' into dev

This should get the dev branch in sync with what's actually on the live server.
- Add a few icons.
- Add a reference to a js file in Page.php
- Ignore everything in protected/runtime and remove any files that are currently in it.
