Filtering :Stacktrace

[tpope]

Switching from passive location list stacktrace retrieval to an active :Stacktrace command means we now have an opportunity to pass parameters, like :Stacktrace +dups -java. The first step is to switch back to the nREPL stacktrace op from the custom eval we're currently using.

In replant I delegate filter to vim-qf and append # into the end of lines.
