Explanation of current behavior:
In the current FS command line implementation, the argument passed to the -c option needs to be the name of a server property file excluding the .conn file suffix, the folder path in which the property file resides should not be included either.  In addition, this property file should be a direct/indirect child of the 'user.home'/.datastudio/connections folder.

For example, if you have a connection file at
   'user.home'/.datastudio/connections/MySQL/MySQL 5.0 Local.conn
then, this file needs to be passed to FS command line as
   -c"MySQL 5.0 Local"

This behavior is inconsistent with the connection string we specify when inside of FS. We should modify this behavior to make it consistent w/ how we connect inside of FS. What to do we do about backwards compatibility?
