gitk: Make gitk dialog windows transient

Transient windows are always kept above their parent, and don't occupy
any space in the taskbar, which is useful for dialogs.  Also, when
transient is used, it is important to bind windows to the correct
parent.

This commit adds transient annotations to all dialogs, ensures usage
of the correct parent for error and confirmation popups, and, as a
side job, makes gitk preserve the create tag dialog window in case of
errors.
