Remove custom conflicting JavaScript snippet.

This was causing warnings every time a new vim instance opened a .js file for the first time. Needless to say, it's annoying. The regression this will cause is that f<tab> will now use "function(${1}) {${2}};" or something like that.

Closes #112.

Bind <prefix> C-l to C-l to restore some way of clearing the shell.

I'm using this with an iTerm2 keybinding, cmd+k, to send the hex codes 0x01 0x0C. I chose cmd+k because that's the keybinding Terminal uses to clear the screen normally.
