Subject: [PATCH] Monitor tags patch

This patch allows you to have different tags icons on a per-monitor
basis. This patch will conflict with a series of other patches, but
it should be more or less straightforward to sort out:
   - LENGTH(tags) is replaced with TAGLENGTH
   - tags[i] is replaced with tags[m->mon][i]
