Full support for node 0.10, 0.11, 0.12 and iojs. Much faster install command without any Buffer out of space errors caused by using exec. Cleanup of tests and REPL/install related files.

• refactor(repl): REPL will now work on all versions of node > 0.8
• fix(repl): Fixed REPL for node <= 0.10.x, should fix #60
• fix(repl): clever repl does not work on node 0.11, 0.12 and io.js
• chore(cleanup): Removed debug log
• fix(modules): Dependencies now install much faster using async smarter + use spawn instead of exec - this makes things much faster and more efficient, as well as ensuring we don't get any Buffer max/out-of-space related errors.
• chore(cleanup): Search related tests
• fix(tests): Removed use of verbose for tests
• fix(tests): REPL Tests updated to work with cli-tables
• chore(cleanup): Build command
• refactor(tests): Linting and Re-indenting tests
• release(1.2.3): Full support for node 0.10, 0.11, 0.12 and iojs. Much faster install command without any Buffer out of space errors caused by using exec. Cleanup of tests and REPL/install related files.
