@tejashah88 Please review/merge.

Closes #58.

This fixes several bugs or obvious misses, too.

• If you specify the same port for HTTP and HTTPs things break quietly, Specifying the same value for http and httpsPort silently broken #61.
• You cannot disable HTTP, There's no way to disable HTTP #62.
• Start returns instance, but we have two instances now, The start method returns a single instance #63
• The test apps were renamed for more consistency, borrowed from Refactored app-server internals. #56.
• There's a more sane use of defaults with lodash, avoiding the whole undefined vs. false confusion, fixing a real bug with debug and verify being not properly defaulted.
