Disables the prior landing page Google Experiment and begins a new one involving the placement and captioning of the button for inviting friends to the user's party.
* Added test for header ctrl
* Made openModal function more readable
* Only show setting to disable invite friends if party is exactly 1 member big
* Use party.memberCount instead of party.members.length because it's more expressive
Health, XP, and Mana bars were broken in IE, due to the use of {{ }} within
style attributes. Using Angular's string interpolation within style attributes
doesn't work in IE, as IE will actually strip the property immediately upon DOM
render. Using ng-style allows properties to be preserved, and renders
cross-browser correctly.
