Backspace support in hidden vars seems to still not work quite right about prompt

[bmeck]

Its a logic error w/ our regexp, going to have to use manual things to do length matching. Current implementation will only handle one backspace at a time. Fixing.

Tests are now passing, but I am seeing an EventEmitter leak when running vows --spec now:

$ vows --spec

info:   Not following instructions will result in test failure
info:   When prompted, enter: 12345 [backspace] [backspace] [enter]
prompt: password:

    ✓ should respond with 123

Wait, I think this might be my fault. Hold on

This was an error in the tests. The event emitter "leak" was not a leak at all. The mock tests were not correctly setting the mock stdin stream so .readLine was called multiple times in parallel thus appearing as if it was a leak.
