[PATCH 07/11] gitweb: Refactor generating of long dates into format_timestamp_html

[Jakub Narebski <jnareb@gmail.com>]

It is pure refactoring and doesn't change gitweb output, though this
could potentially affect 'summary', 'log', and 'commit'-like views
('commit', 'commitdiff', 'tag').

Remove print_local_time and format_local_time, as their use is now
replaced (indirectly) by using format_timestamp_html.


While at it improve whitespace formatting.

This helper subroutine would reduce a bit code repetition that can be
found in original J.H. patch.
