[PATCH] gitk: add a checkbox to control the visibility of tags

["Łukasz Stelmach" <stlman@poczta.fm>]

Enable hiding of tags displayed in the tree as yellow labels.
If a repository is used together with a system like Gerrit
there may be quite a lot of tags used to control building
and there may be hardly any place left for commit subjects.
