Summer Cleaning for the KDE 4.1 Release

Today, I decided that I’ll stray away a bit from my GSoC work and do some summer cleaning (as against spring cleaning) for the KDE 4.1 release. Fixed a few minor bugs, and regressed one patch.

I made three commits:
1. Removing Earth from the Conjunctions tool UI
2. Regression on an earlier bugfix, because it was applied twice
3. Some more fixes for the Angular Distance tool
