Actually compare `has('timers')` to something :/

This properly deals with versions of VIm that don't support timers. So
that older versions of Vim still work but run into the bug where some
panes get insertmode inappropriately set.

 ## Usage
 
 Most keybindings should work as you might expect from, say Atom or Sublime Text; `SHIFT+ARROW` to select and `CTRL+C/V` to copy/paste. But don't expect Vim to completely bend to your will, it is still useful to familiarise yourself with some of Vim's basic concepts. For instance you may on occasion find yourself stuck in a particular Vim mode, like when pasting text without 'Paste Mode' then inserted text can trigger random mappings. In such case `CTRL+Q` may not kill Vim and you'll need to find a way of getting to Normal Mode and typing `:q` then `<RETURN>`. Such is life with Vim, this plugin is highly unlikely to ever change that. (BTW conventional pasting is on by default, but to exit an errant 'Paste Mode' use `:set nopaste`.)
