Adds a new autocommand, TextPutPost. This autocommand fires when the
user puts text with p or P.

The motivating feature for this change was to implement a plugin that
"carries" Java imports between files. I.e. yanking from one java file
and pasting into another would automatically add the imports required.

This flag, denoted by an 'f', will force the character over the
colorcolumn to take on the colorcolumn's highlight, discarding any
highlight the character would have had otherwise.

This is the inverse of the 'background' flag, where the colorcolumn will
take the highlight of the character discarding any highlight it
otherwise would have had.

Problem:
When a TUI client is suspended it still receives UI events from the
server, and has to process these accumulated events when it is resumed.
With mulitple TUI clients this is a bigger problem, considering the
following steps:
1. A TUI client is attached.
2. CTRL-Z is pressed and the first client is suspended.
3. Another TUI client is attached.
4. CTRL-Z is pressed and a "suspend" event is sent to both clients. The
   second client is suspended, while the first client isn't able to
   process the event because it has already been suspended.
5. The first client is resumed. It processes the accumulated "suspend"
   event and suspends immediately.

Solution:
Make a TUI client detach on suspend and re-attach on resume.
