ST sort tabs (neater)

SortTabs.py

import sublime, sublime_plugin, os
from operator import itemgetter

class SortTabsCommand(sublime_plugin.TextCommand):
	def run(self, edit):
		file_views = []
		win = self.view.window()
		curr_view = win.active_view()
		for vw in win.views():
			head, tail = os.path.split(vw.file_name())
			group, _ = win.get_view_index(vw)
			file_views.append((tail.lower(), vw, group))
		file_views.sort(key = itemgetter(2, 0))
		for index, (_, vw, group) in enumerate(file_views):
			if not index or group > prev_group:
					moving_index = 0
					prev_group = group
			else:
				moving_index += 1
			win.set_view_index(vw, group, moving_index)
		win.focus_view(curr_view)

No added functionality, just slightly neater code.
