Mac/Extras.install.py，Can not filter osx DS_store file

As

ifname=='.DS_store': return0

But in OSX, Real File Name is .DS_Store, like this

(venv) zhangbo@zhangbodeMacBook-Pro a2 % ll -a
total 16
drwxr-xr-x 4 zhangbo staff 128 Oct 22 17:34 .
drwxr-xr-x 8 zhangbo staff 256 Oct 22 17:18 ..
-rw-r--r--@ 1 zhangbo staff 6148 Oct 22 17:17 .DS_Store
drwxr-xr-x 3 zhangbo staff 96 Oct 22 17:23 123

So we need update .DS_store to .DS_Store

Suggested change

	ifname=='CVS': return0
	ifname=='.cvsignore': return0
	ifname=='.DS_store': return0
	ifname=='.DS_Store': return0
	ifname=='.svn': return0
	ifnamein ('CVS', '.cvsignore', '.DS_store', '.DS_Store', '.svn')`:
	return0

A proof-of-concept:

>>>deftest(name):
... returnnamein ('CVS', '.cvsignore', '.DS_store', '.DS_Store', '.svn')
...
>>>test('fooCVS')
False>>>test('foo')
False>>>test('CVS')
True
