[PATCH v2 2/3] gitweb: introduce localtime feature

[Kevin Cernekee <cernekee@gmail.com>]

With this feature enabled, all timestamps are shown in the local
timezone instead of GMT.  The timezone is taken from the appropriate
timezone string stored in the commit object.

Affected views include:

summary page, last change field (commit time from latest change)
commit page, author/committer
commitdiff page, author/committer
log page, author time

No change to:

relative timestamps
patch page
