Initialization Option: completion.overwriteFollowingIdentifier

Browse Source 
Previously, ccls overwrites the identifier immediately following the
cursor on completions. Some user does not want this behaviour.

This commit introduces a new initialization option:
completion.overwriteFollowingIdentifier, which allows
customizing the said behaviour.

fix #678.
