Alpha 14 Update - Menus and Bug Fixes

Most of this update is just improvements to the audio/visuals of the game. I wanted to finally add in button sounds and remake some of the more outdated menus just because I was starting to get annoyed at how bad they were. I now intend to work on some more game-play stuff again, but figured it would be a good idea to release the current changes first as they should not break the game.

• Fixed some issues with map screen overlaps
• Added a basic turn summary that appears at the start of each turn
• Made some updates to the diplomacy meeting screens, adding some new effects to improve the screen
• redid the empire information screen, adding in more options and information
  • This includes having 3 different lists of empire planets (overview, military, production)
• Redid the buildings screen
• Redid the fleets screen (still WIP, but better at least)
  • All columns can also sort by the selected value now
• Also made a graph of empire production allocation
• Made some changes to the tech screens
• Started updating the ship design screen
• Created a custom mouse cursor
• Added UI noises for all buttons
  • Selections have one noise, going back another, and errors a third.
  • Current sounds are likely temporary until I make a better set of sounds
• Updated a few empire portraits
  • Brotherhood of Atom finally have a different set of pictures compared to the other human faction
• All updated lists can now sort by column values, either by letter or by number value

Did some other minor updates to menus

• Fixed some screens allowing scrolling of the map when it is out of view
• Fix exploits (Ship design save could be done multiple times, gaining more money)
• Fixed an issue with turn one population increases being unusually high
• Fixed an issue with diplomacy in single player not allowing alliances in some instances
• Fixed some other issues with the ship design menu
