Title: visit-source improvements

Rails view errors are reported with:
On line #20 of app/views/...
so the regexp needs line first, then file.

With a prefix argument, prompt for Source location and default to the
interprogram-paste-function so you can copy from output outside of Emacs and
[C-u f2 RET] to quickly get to the given location.
