QA Campaign System v1

[iamsirenstorm]

Summation of remaining tasks to push the Campaign System to QA:

• Fix svgloader crash (svgloader crash when using non-native resolutions in windowed mode #131)
• Fix crashes related to resuming campaigns from the main menu
• Fix being unable to change campaigns (after having loaded into one already) (seems to only be a problem for campaigns that feature background maps)
• Change UI behavior from booting the user out when loading a campaign menu without it mounted to start with
• (HIGHLY PREFERRED) Add API method to Panorama to get the .assets folder
• Panorama Feature Request: Force reloading on image elements #150
• Fix controller being unable to invoke the Pause Menu (not really required but nice to have since controller support is shipping with no-nav-bar) (Bug: Unable to invoke the pause menu while in-game using a controller #148)
• Fix controller scroll panel behavior (cannot hold down button to scroll down) (not really required but nice to have since controller support is shipping with no-nav-bar) (Bug: (Controller) Unable to repeatedly move focus while holding down a direction #149)

Crash reports will have their description with "Campaign System v1 Crash" if that helps with finding them.

Would be fun to replace svgloader with rsvg eventually...
