This is a slow implementation; it runs svn log once per file
still, rather than running svn log once on the whole srcdir.
I did it this way because in my experience, svn log, run on a directory,
does not always list every change to files inside that directory.
I don't know why, and I use svn as little as possible these days.
* Automatically run --gettime the first time ikiwiki is run on
a given srcdir.
* Optimise --gettime for git, so it's appropriatly screamingly
fast. (This could be done for other backends too.)
* However, --gettime for git no longer follows renames.
* Use above to fix up timestamps on docwiki, as well as ensure that
timestamps on basewiki files shipped in the deb are sane.
* Rename --getctime to --gettime. (The old name still works for
backwards compatability.)
* --gettime now also looks up last modification time.
* Add rcs_getmtime to plugin API; currently only implemented
for git.
The pagetemplate hook may be called multiple times, for example when pages
are inlined into a page. Sidebars were being calculated each time that
happened, only to be thrown away when the final pagetemplate hook was
called. Avoid this unnecessary work.
Remove stored sidebar content on use to save some memory.
This way, the example blog always has a sidebar on the index page,
but not the overhead of sidebars on all the other pages. And if a
user wants to, they can enable global_sidebars to switch to sidebars on
every page.
Added a visible border; tuned down the whitespace/borders.
Note the use of the -1 pixel margin-top -- this makes the sidebar appear
to hang down from the line under the actions at the top of the page.
* pagestats: Class parameter can be used to override default class for
custom styling.
* pagestats: Use style=list to get a list of tags, scaled by use like
in a tag cloud. This is useful to put in a sidebar.
* Rework example blog front page.
