Fix CRLF line endings in Documentation/input/iforce-protocol.txt

Emil Medve points out that this documentation file uses CRLF line
endings, which means that if you use

[core]
autocrlf=input

(which makes sense if you ever develop under Windows, for example, or if
you use other broken tools) in your git config, git will always complain
about the file being dirty.

This removes the bogus DOS line endings, and removes whitespace at the
end of line.
