gitweb: Whitespace cleanup: realign, reindent

This patch tries (but no too hard) to fit gitweb source in 80 columns,
for 2 columns wide tabs, and indent and align source for better
readibility.

While at it added comment to 'snapshot' entry defaults for %feature
hash, corrected "blobl" action in git_blame2 and git_blame to "blob",
key of argument to $cgi->a from 'class' to '-class'.
