[Feature] Add option to call manually without callto link

[ThaDaVos]

As callto can't be passed from RDP to Client, it would be great if the software allowed to manually enter a phone number and call it

Hello!

I can probably make a simple GUI to input a number in.

The program it self technically can be made to work with anything that can call it and pass a number as launch argument.
So you can possibly pass it from other software, or use something like a .bat file to pass it a number manually.

@echo off
set /P Number="Input number to call: "
YDialer.exe %Number%
