Determine if app is run by haxelib instead of assuming it always is

[T1mL3arn]

When you run compiled app not from haxelib (like during some development or testing) there is a bug when mlib losts the last passed argument. E.g. passing these three args with neko run.n foo bar . seen by mlib like foo bar (without the last dot). This happens in Console.hx

mlib/src/massive/sys/cmd/Console.hx

Lines 209 to 213 in 9888685

	/**
	* Strips the dir path from the end of the args array.
	* This is the path from where haxelib was called
	* */
	private function getCurrentDirectoryPathFromArgs(a:Array<String>):File

because it is always told it is a haxelib run.
