Improve UI to reduce confusion about Firewall state

[oper8]

Enhancement suggestion:

Instead of using only an icon to indicate the firewall state on the main screen, add the caption "Enabled" or "Disabled" to clearly indicate the current firewall state. For example: "AFWall+ Enabled" or "AFWall+ Disabled"

Also, the menu option to enable or disable the firewall should indicate the action to be taken rather than the current state of the firewall. For example: "Enable Firewall" (if currently disabled), or "Disable Firewall" (if currently enabled).

To the first point, if use enable multiple profile it won't be visible. I'll think second point will improve the state better.
