XCode: trim the project path. (#69)

* XCode:  After the user drag and drop the project file to the console, it will trim the project path.
characterSetToRemove {"\n", `'`, `"`}

* common.go:
 - trimProjectpath method fix - Infinite loop removed. It will trim every ', ", character
 - contains method removed (Already have one as a util.)

common_test.go: The "Multiple" test case has been removed. (Because we don't use multiple trim)

xcode.go: clean
