Enabling implicit appbase (dnx . run -> dnx run)

Before providing appbase folder was necessary. Now we don't expect a folder anymore but assume that the current folder is the appbase folder. The only exception is where for backwards compatibility we continue to recognize `.` (so `dnx . run` continues to work). If the user really wants to provide a folder that is not the current folder they need to use the --appbase parameter.

Fixes #1403
