Dan Kegel

Don't detect desktop environment, detect individual programs.
Make warnings more obvious on console.
flash: updated
gecko: updated
ie6: improved prerequisite checking
psdkwin7: requires native gdiplus for the moment, so make that a
prerequisite for now

Austin English

Don't consider missing cabextract fatal, unless it's actually being used
Don't use cabextract directly, use the wrapper for all uses (issue 95)
Use a more sane path for C:. Patch from 'arielco'. Issue 96.
adobeair: add to winetrickstest, add missing decorations
dotnet20: Check for mscorlib.dll rather than l_intl.nls
icodec: remove, it's no longer online
mpc: Update

Andrew Nguyen

Suppress STDERR messages from which command
7zip: added
adobeair: added
d3dxof: added
msxml4/msxml6: add override before installing
vc2005trial: Use 7-zip to extract the UDF image rather than mounting
it (so we can avoid sudo/root)
