Completions: move continuations upper in proposals list.

Browse Source 
Since fuzzy completions are allowed, the lexicographically first proposal
is not necessarily most relevant. The patch modifies sorting of proposals
so that the exact match and continuations go first, and fuzzy completions
follow.

Moreover, being a continuation seem to be a more important characteristic
of a proposal, than being it a function argument or keyword etc. That's why
the check for continuation is placed before the check for order.
