Back-end:
 - bug fixes
 - added new script property - sysname. 'path' is used for starting scripts, 'sysname' is used for stopping scripts. The 'sysname' is how Forever sees the script. It's different when the script is started from terminal and when it's started from the GUI.
- the GUI now preserves the scripts order
- fully tested functionalities - refresh, start/stop, rename
