Summary

lens_format_shutter: use rounding consistent with Canon's for 1/25 and faster shutter speeds ( http://www.magiclantern.fm/forum/index.php?topic=10648 )
LV ISO display: in movie mode, read it from FRAME_ISO and include the effects of ML digital ISO, FPS override corrections, full-stop rounding with raw video (should be similar to the one before LVinfo refactoring). Should fix issue #1741, to be tested.
500D: slowed down bmp_fill (helps with ERR70 while recording)
edmac_memcpy: removed the "else" branch for free EDMAC channels. If this breaks any builds, you know what you have to do ;)
500D: fix EDMAC channels (raw video now working)
50D: allow expo override to sync with dialed exposure values (should fix issue 1968, to be tested)
500D: FRAME_SHUTTER_TIMER is wrong (fixes issue #1983)
Arrow shortcuts: when they depend on the LCD sensor, print info about how to enable it (500D, 550D, 650D, 700D)
Menu: print long help lines with condensed font (to make sure they will not overflow)
Font backend: fix displaying justified strings (was trimming the last character when printing condensed text)
500D: FRAME_ISO is OK for reading
Merged in Audionut/branch-fix/Help_text (pull request #490) Small fixes and updates to help text.
More verbose bracketing help
Fix AF_BACK_BUTTON depend on 5D3 (thanks a1ex)
