Allow using nested data folder

[crile]

Hi, thanks for this program.
Is there a way to modify manually the rules ?
Like copy the "data" directory in the same directory than the executable ?

@crile @Atavic Files in data folder are embedded in the executable. But i can implement a new feature to use the data folder if it exists.

Ok, thanks. I think it can be a good feature without too much trouble to develop (I know nothing about go language :'(, else I could do it myself)

@crile With latest release (4.12.0) you can extract the current data and use your own :

To use the data in the nested folder, you have to set option useEmbeddedData to false in app.conf.
