number in list; copy number; change git command

The item number now shows before the item title in lists.

Pressing a modifier key on a list item copies the item number.

Git branch command got a little crazy... now checks out develop, pulls
latest from origin develop, then checks out the new branch. (Sure,
this might cause some problems... if you need to merge, etc. but
for me for now it's handy.) (Although I probably should've made this
change on a separate commit.  Lame.)
