[wp-hackers] register_settings and admin_notices

@ Mohammad and Glenn,

Thanks for the feedback guys. Your comments gave me some ideas which led to
the following solution:

A conditional inside the register_settings() callback function checks if the
Settings page Reset checkbox has been checked. If true, it adds a new option
to the options array, called 'just-reset' with a value of 'true'. Then in
the admin_notices function, if 'just-reset' is true, the function outputs
the customised message. If the Settings page is updated without Reset,
'just-reset' is set to 'false', and no custom message is displayed. The
admin_notices function also checks the plugin's pagehook before doing
anything (good point, Glenn).

Plus, I can use the same method to add other validation messages, if
required, all hooked into admin_notices.

This works well, functionality-wise. I guess the only downside is the db
write and retrieval of the 'just-reset' option, but I don't think this is
really an issue given it's only happening in admin.

If anyone can see a better way, the feedback will be very welcome.
