Replace deasync, inquirer, or both

[MathieuAA]

The deasync package must either be replaced, or a fix must be found.

See #12 for more details.

Apparently, using NodeJS on Windows can be troublesome (some tools may not be installed, etc.).

Update and end: instead of replacing, we could just not use any of them (inquirer and deasync), and still keep them in the code.
This is the main idea: we could just not require the user for his/her input, and just pick the one editor we can't detect (right now it's UML Designer). If, however, we decide to add another editor that can't be detected either, then the user would have to pick the right one with inquirer (thus the call to deasync).
Better safe than sorry.
It's currently being maintained in a separate branch that wil, hopefuly, be merged ASAP.

It's not a perfect solution, but we hope in the future that the great JDL and the soon-to-be UML editor will replace the editors out there.
