ubiquity: strip '$' in shell snippets

stripShellPrompt.js

/*
 * Strip the characters of the modifier in the input
 * This was motivated by the desire to strip '$'s in shell snippets,
 * so as to copy and paste in a running terminal.
 * TODO: Add support for stripping 'eric@schemer$ ' for example.
