Minor optimizations using private, params, and isEqualType (#4323) * Optimizations with private, params, and isEqualType * Fixed tab being used instead of space * Fixed tabs inserted by notepad++ * More usage of new private syntax and params - changed a few checks for an array being empty to `_arr isEqualTo []` rather than `count _arr == 0` - added more uses of `private` on the same line as the variable is declared - added more uses of params to assign variables passed as parameters - removed unnecessary parentheses - removed several unnecessary variable declarations with private array syntax * clean up and formatting 2016-09-04 14:44:22 +00:00			`private ["_seeker", "_targetPos", "_seekerMaxAngle", "_sensorPos", "_testPointVector", "_testDotProduct"];`
