UI quality-of-life improvements

[RadHazard]

Hi there! I've been playing with this mod for a little while now, and I've had a few ides for quality-of-life improvements to the UI, mostly centered around Mission Profile management.

I was in a coding mood today, so I decided to put all my ideas together and submit a pull request for them. I've tested the changes locally and have confirmed that I can launch all the various mission types and rename/delete profiles without any issues.

Let me know if you've got any questions or if I should change anything!

Full List of Changes

• The list of mission profiles highlights the cost in green, and also shows cost per ton (useful for construction missions)

• The mission profile list is now sorted by name (and updates when profiles are renamed)

• Transport profiles are no longer shown when picking a mission profile for a Deploy mission, and vice-versa

• Profiles of the right type but not valid for a mission (e.g. because the payload is too heavy) are hidden by default, but can be shown with a checkbox

• The list of profiles can be searched by name (either profile name or craft name)

• Both the payload search and profile search are now case-insensitive

I'll be reviewing this in a day or so, are there any other changes?

I'm merging this into a local branch to test first, thanks, looks very nice
