Make process/application/executable consistent accross the software

You have:

* the **Applications** tab
* **Application rules** in the rule tab's left bar, which is bad naming because your rules might have nothing to do with processes and be only about host, PID, port, etc. No application here. I suggest something along the line of "Time scope" but I am not very good in English so your call... >.>
* **Process** in the event tab
* **Applications** when editing a rule
* **From this executable** when editing a rule
* **from this executable** in the pop-up

See, you have three different names for the same concept. It confused me a lot when I started using OpenSnitch because I wondered if they had different meanings, which is not the case. An "executable"... Isn't that a Windows thing?
I know OpenSnitch wants to be an application firewall but I suggest to rename all those instances as *process*. The "processes" tab, "from this process", etc. At least, to be consistent across the whole software. Thanks.
