WikiPageRename doesn't refresh tags

[anjiro]

After using WikiPageRename I would expect wiki#tags#get_all() to include the updated page name, but it still has the old name. I think the right fix would be to change the filename everywhere it occurs in s:tags.collection in autoload/wiki/tags.vim, but that requires extra global functions so I'm hesitant to take a stab at a pull request.

A simple fix would be to refresh all tags. I.e. simply add call wiki#tags#reload() at the end of wiki#page#rename. Do you see any reason why that would not resolve your issue (just wondering if I'm missing something, here)?

Perhaps the minor inconvenience would be that parsing tags may take some time. I am considering to put the tags into a cache to avoid parsing all files everytime. It should be quite simple and would speed up the tag feature quite a lot in big projects, I believe.

I think that the wiki#tags#reload() approach would probably work fine, but indeed might take a bit of extra time. For my scale of wiki right now I think it would not be particularly problematic.

Ok, I've implemented this now, including the caching. Can you test?
