.aliases: Add `-F` to `ls` aliases

Don’t do this for the default `ls`, though.

Closes #234.
bin: Point `subl` to the default ST3 location

Sublime Text 3 does not use the `/Application/Sublime Text 3.app` folder by default. It uses `/Application/Sublime Text.app`.

Closes #232.
.gitconfig: Remove global remote branch

This causes duplicate remotes to be created, potentially leading Git to throw errors when `push`ing.

Closes #215.
.aliases: Add `chromekill` to kill all Chrome tabs to free up memory

Useful when you have a lot of tabs open (which I always do), but you don’t want to close them.

Tabs in Chrome are just processes, so we just filter out the ones we want, and kill them.

Closes #236.
