CMParts: Allow CompCache size to be set by user - via % of total RAM

Use % instead of a set size - per suggestion from Cyanogen
Fix to integer instead of decimal being passed around - props to Nameless
Handle older versions changing enabled CC to Default CC size (25%)
Enable PerformanceSettings dialog to view new CC setup
Final cleanup and fix default values / bash arithmetic
