Add automatic completion display in prompt mode

Browse Source 
Controlled by the autoshowcompl option
Completers now take a CompletionFlag parameter, used to specify
we want fast completion (tag completion can be slow, we do not
want to run it if not explicitely wanted by the user).

@ -394,6 +394,8 @@ Some options are built in kakoune, and can be used to control it's behaviour:
candidates exist, enable completion with common prefix.
* +incsearch+ _bool_: execute search as it is typed
* +autoinfo+ _bool_: display automatic information box for certain commands.
* +autoshowcompl+ _bool_: automatically display possible completions when
editing a prompt.
* +ignored_files+ _regex_: filenames matching this regex wont be considered
as candidates on filename completion (except if the text being completed
already matches it).
