Add line carrying, will carry lines that should be.

Matchers are customizable and can be add-to-list'd to the
cisco-router-matchers list. They simply need to return a "string" to be
carried down.

Activate using C-j or 'cisco-router-carry-line by default.
Change default carry to 3 lines
Add support for a default appendage to the carried line
Work around a legacy indent thing, kinda sucky, but I'll revamp.
