Make guest account name customizable

[Laércio de Sousa]

It would be useful if LightDM allows one to customize guest account credentials (display name in greeter, GECOS, username). A special use case for this feature is in school labs where guest accounts are often used for generic student login, so changing the credentials to "Student" instead of "Guest" would be desirable.

Implementing this feature in LightDM itself is quite easy (just a matter of editing guest-account script), but it's a little bit harder in greeters, because Guest display name is currently hardcoded.

I suggest adding the following entries in lightdm.conf:

[LightDM]
guest-account-username=user # Runs "mktemp -td user-XXXXXX" in guest-account script to set USER and HOME variables
guest-account-gecos=Custom User # pass option '--gecos "Custom User"' to command adduser in guest-account script.

Maybe add Guest Session manager for Users Account, than disable, enable or change your name!!
