[FEATURE] Reset profile back to defaults.

[cecoates]

Is your feature request related to a problem? Please describe.
When I first installed SWICD I played around with the default profile. I've now messed it up beyond recognition and there's no way to restore the original default profile.

My fault, but was trying to learn by doing, so to speak.

Describe the solution you'd like
A reset button to restore the defaults.

Describe alternatives you've considered
I've tried uninstalling SWICD and making sure the SWICD directory is deleted. I'm not sure where the profile is being stored, but my (messed up) config is still the default even after a fresh install.

Edit: Just realized the profiles are stored in Documents, in a folder named SWICD. Deleting the file app_config.conf and relaunching SWICD will restore the default profile.
