Cleaned the gui a little bit:

- added a checkbox to control the use of external servers for ip determination.
- put back Network on the left
- put channels out of RS_RELEASE_VERSION, as it's not working yet.
- NetworkDialog:
	- set the info in columns about trust to be more explicit
	- changed dark green into light green to comply with colors in the trust matrix (it's also more readable in light green)
	- corrected trust strings that appeared in the Last Contact column
- changed "generate certificate" in connect friends wizard into "export my certificate..." which is more appropriate
