better CLI args/parser integration

First, this commit adds a shortcut if only a single argument is given
that can be parsed as a regex. This is to retain the old behaviour of
"raidgrep NAME" just working, without needing to specify -player or
anything.

Secondly, this also re-wraps arguments with spaces (unless there's only
one argument in total). This means that the following should work:
    raidgrep -- -player "Godric Gobbledygook"
instead of either
    raidgrep -- '-player "Godric Gobbledygook"'
    raidgrep -- -player '"Godric Gobbledygook"'
(notice the extra quotes).
