[PATCH v2] gitk: make pointer selection visible in highlighted lines

[Max Kirillov <max@max630.net>]

Custom tags have higher priority than `sel`, and when they define their
own background, it makes selection invisible. Especially inconvenient
for `filesep` (to select filenames), but also affects other tags.
Use `tag raise` to fix `sel`'s priority.

Also change `omark` tag handling, so that it is created once, together
with others, and then only removed from text rather than deleted. Then
it will not get larger priority than the `sel` tag.
