Core-165: Change environment objects status only when a reply or sensor ...

Now object status is updated only when a executed=true plugin's reply is received. This default behavior can be turned off adding adding a 'send-and-forget=true' property in the command.

EXAMPLE: Before this change
Time             Action
0sec             Turn on livingroom light
+1sec           Zway plugins receves the command and starts execution
+1sec           Freedomotic updates the object status and changes the icon 
 
EXAMPLE: With this change

+3sec           Zway replies to freedomotic the command is executed succesfully
+4sec           Freedomotic updates the object status and changes the icon  

Default plugin's reply timeout is 10 seconds if a custom value is not set in the command
