When a ref refers to something other then a commit or tag object, cgit
could segfault when trying to display the tag info.

When a lightweight tag is referencing a commit object, cgit now uses
the commit date when comparing tag age. Also, the commitdate and author
info is printed in the refs view, making lightweight tags appear similar
to annotated tags.

The snapshot function has only been linked to from the commit page while
users often would want to download a certain release. With this patch,
direct download links will now be printed for each tagged release on the
repo summary page.

Some users prefer to see the full message, so to make these users happy
the new querystring parameter "showmsg" can be used to print the full
commit message per log entry.

A link is provided in the log heading to make this function accessible,
and all links and forms tries to preserve the users preference.

Note: the new link is not displayed on the summary page since the point
of the summary page is to be a summary, but it is still obeyed if specified
manually.

This is finally a proper headerfile for the shared ui-functions which
used to reside in cgit.h
