Basic Budget Functionality

[jasonjohnson]

Introduce basic budget functionality with user interface support.

The basic features must give the player control over per-unit budgets, visibility into the configuration of budgets, and visibility into budget cycle timing. Budget functionality indirectly provides a way to destroy units (by underfunding unit-level budgets, units will self-destruct at random) and preserve resources (by reducing budget to avoid bankruptcy).

Simulation:

• [ ] Use budget configuration from the interface

Interface:

• [x] Progress bar
• [ ] Text field with read-only state
• [x] Vertical layout helper
• [x] Horizontal layout helper
• [x] Variable button sizing, ex: 9-slicing, potentially using label size to auto-size

Graphics:

• [x] Progress bar
• [ ] Text field with read-only state

Sound:

• [ ] Play a pleasing click or tap when budget +/- buttons are clicked
• [ ] Play an informative ding at the beginning of each budget cycle (when the progress bar resets)
