Improved exploration screen

New things this week:

1. Changed the active effects windows so the effects are easier to read.
2. Now you can see the base on the planet map. You can enter inside too.
3. Fixed being able to click map sectors outside of the window area.
4. Fixed some visual glitches with the tooltips.
5. Fixed opening multiple windows when inspecting entities.
6. Added tooltips to the icons in the active effects section of the explore screen.

This week was mostly bug fixes, next week I'll work on improving the exploration experience because I still feel it's not good enough.
