New in version 5:
- added Gif Only Mode
- added Select All / Select None to Download Manager (probably works best with Gif Only Mode)
- added Auto Advance toggle (if auto advance is disabled, it only advances to the next image unless you click the screen)
- attempt to fix "bmp.IsOk()" error
- removed checkboxes from beside the board names, since they didn't actually do anything and just confused people
New in version 4:
- I CAME (statistics)
- faster loading (fixed a bandwidth bug)
- auto-detection of speed for gifs: works best if it's 1 stroke per animation length, but can be specifically set in post text, or in dispdata.cfg.
- regular expression spam filter: each line in spamfilter.cfg is used as a regex against the OP text for a thread, if it matches, the thread won't be shown in the download manager.
New in version 3:
- auto-detection for count/speed/force
- probably other stuff, I forget
