Start Menu and Loading Screen Expansion Update

Included in this update...

* A fix in the StartMenu level that gets rid of the bug formerly
blacking out the screen, blocking access to Level 1, etc.

+ A new background texture and positioning reconfiguration (to be
finalized...still strange on some resolutions) that is smaller with more
button options, and (based on resolution) may be centered.

+ Full-screen windows appear for specific options in the Pause Menu

* Pause Menu variables reconfigured to allow for switching between menu
and screens that were launched by the menu. This allows for labels,
buttons, etc. to stop running into each other.

* Temporary background given to Start Menu...which must be changed soon!

+ New Buttons (besides those of Apr 13 update, which was reverted)

* Changed color scheme (Yellow/Orange to Grayscale)
