Everything_autolaunch should be able to specify an alias path

Now we can specify an absolute path for everything_autolaunch.such as:
everything_autolaunch: N:\Tools\Everything\Everything.exe

We also can use relative path:
everything_autolaunch: ..\..\Everything\Everything.exe

If alias path is supportted, it would be more convenient, when switching to another PC.
such as: ALIAS /Tools → N:\Tools
everything_autolaunch: /Tools\Everything\Everything.exe
or:ALIAS /Everything.exe → /Tools\Everything\Everything.exe
everything_autolaunch: /Everything.exe
or:
everything_autolaunch: /home\Everything\Everything.exe
