str formatcmd
Prevent the :format command from triggering hooks. The :format command is often called from a BufWritePre hook to format the current buffer, however the :format command itself calls `:write` to store the buffer in a temporary location, potentially causing an infinite recursion. If we disable hooks while running :format, there's no danger of that occurring.

Do not reparse %sh{...} strings Automatic reparsing of %sh{...}, while convenient in many cases, can be surprising as well, and can lead to security problems: 'echo %sh{ printf "foo\necho bar" }' runs 'echo foo', then 'echo bar'. we make this danger explicit, and we fix the 'nop %sh{...}' pattern. To reparse %sh{...} strings, they can be passed to evaluate-commands, which has been fixed to work in every cases where %sh{...} reparsing was used..

Introduce `formatter.kak` to handle formatting. The modified files used to handle formatting code with the same code, and a different command, the process is now centralized into a single file. Language support files should set the `formatcmd` string to whatever formatter is the most popular in their respective community, eventually with default options.
