Typofix and loading emulators on windows

[multimokia]

Fixes #39

Windows terminals (cmd, powershell, gitbash, etc.) all support the use of forwardslash (/), so allowing it in the path is acceptable. As such, I removed the check for forwardslashes in the path and just allowed it, which works on my machine running windows 10.

To preserve backslash functionality, the command still wraps the path in quotes. Additionally, since getEmulatorPath was the same function as getPath with the additional handling for the aforementioned issue, I removed the function.

I also made a typofix to the error message: you Android emulators! -> your Android emulators! and did some cleaning up here and there to keep things tidy.
