Mercurial bundle fix

Mercurial bundle was failing for me for some time and I finaly decided to fix it.
Below is the patch fixing the error. Apparently the com.macromates.textmate.plist file doesn't
always have the 'OakTextViewNormalFontName' property. I checked standard bundles and found
in the TextMate.bundle almost same code but with defaults for font name and size.
Corresponding change for Mercurial is in the below patch.
