tigefa4u projects Trac

db: Added a missing space in an SQL statement. Related to #8751.

TracBrowser: improve keyboard navigation
- uses 'L' for log shortcut (so this leaves us 'l' available for another use, see #7867)
- 'o'pen, 'v'iew, 'A'nnotate or 'reload' the entry under the mouse, if no current row has been selected yet with 'j' or 'k'
- a few more code clean-ups

db: Mostly cosmetic fixes related to #8751, and fixed #9059 as suggested in comment:1:ticket:9059.

#8751: most of the changes did happen on trunk recently, removing the branch.

l10/he: remove .mo file added by mistake

versioncontrol: added a test for `CachedRepository.sync_changeset`, which catches the #9060 issue.

+ the fix...

versioncontrol: added a test for `CachedRepository.sync(clean=True)`

versioncontrol: refactor cache tests, hopefully a bit clearer now.

trac-svn-hook: made the call to `trac-admin` asynchronous, as otherwise an svn commit takes way too long on the client side.
