#1 Multiple key bindings for conversions

[Chris DeLashmutt]

Currently, the plug in only allows for one set of
regular expressions and replacements. It would be nice
to be able to have multiple conversions that one could
assign to different keys.

For instance, I might want to have one set of
conversions that performs one task that is assigned to
CTRL-SHIFT-V, and another set of conversions that is
assigned to CTRL-SHIFT-B, and so on.

This would allow the plug in to serve for more than
just one job at a time!
