fixed replay structure/functionality and modularized some Scorebar drawing methods. Also fixed upgrade bouncing (it no longer does it)....

updated start menu to include upgrade descriptions. added multiple life functionality. Player.hasUpgrade functionality still in place for extensibility
(i.e. shields)

Potential adds: choose your color, choose your name, choose your difficulty (nLevels?)
An "interface" for highlighting buttons and so forth would be an interesting sideproject. specify a layout and keyadapter for navigating.
would also require draw routines to match...
