Natural Selection 2 - Update

Balance
- Changed combat time-out to 3 seconds (was 1.5) seconds (makes Regeneration and Cloaking less powerful and easy to use).
- Reduced Shade cloaking radius from 20 to 14.
- Re-balanced Crags so they now self-heal, but only give 3% health every 2 seconds (min 10, max 40). (was 5%, min 10, max 50).

Fix
- Fixed error when starting Explore mode.
- Fixed bug where Crags were getting too much health.
- Fixed crash when a render_setup file could not be parsed due to improper formatting.
- Fixed bug where text with multiple lines was not properly printed to the console.
- Fixed bug where the spinner on the loading screen did not display if texture quality was set to medium.

SDK
- Added a second parameter to the callback called from Shared.SendHTTPRequest in the case of an error, which specifies the error message.
- Changed models to use a default material if one wasn't specified in the imported file.
