Notes on properties and ini files, reset and reset to default.
----------------------------------------------------------------------------
Each ini contains a complete option set.

Priority order for option sets (Lowest to Highest):

built-in defaults
program    ini (executable root filename ini)
debug      ini (if running a debug build)
vector     ini (really is vector.ini!)
vertical     ini (really is vertical.ini!)
horizont     ini (really is horizont.ini!)
driver     ini (source code root filename in which this driver is found)
grandparent ini (grandparent, not sure these exist, but it is possible)
parent     ini (where parent is the name of the parent driver)
game       ini (where game is the driver name for this game)

To determine which option set to use, start at the top level (lowest
priority), and overlay all higher priority ini's until the desired level
is reached.

The 'default' option set is the next priority higher up the list from
the desired level. For the default (program.ini) level, it is also the
default.

When MAME is run, the desired level is game ini.

Expected Code behavior:
----------------------------------------------------------------------------
This approach requires 3 option sets, 'current', 'original' and 'default'.

'current': used to populate the property pages, and to initialize the
'original' set.

'original': used to evaluate if the 'Reset' button is enabled.
If 'current' matches 'original', the 'Reset' button is disabled,
otherwise it is enabled.

'default': used to evaluate if the 'Restore to Defaults' button is enabled.
If 'current' matches 'default', the 'Restore to Defaults' button is disabled,
otherwise it is enabled.

When editing any option set, the desired level is set to the one being
edited, the default set for that level, is the next lower priority set found.

Upon entering the properties dialog:
a) 'current' is initialized
b) 'original' is initialized by 'current'
c) 'default' is initialized
d) Populate Property pages with 'current'
e) 'Reset' and 'Restore to Defaults' buttons are evaluated.

After any change:
a) 'current' is updated
b) 'Reset' and 'Restore to Defaults' buttons are re-evaluated.

Reset:
a) 'current' is reinitialized to 'original'
b) Re-populate Property pages with 'current'
c) 'Reset' and 'Restore to Defaults' buttons are re-evaluated.

Restore to Defaults:
a) 'current' is reinitialized to 'default'
b) Re-populate Property pages with 'current'
b) 'Reset' and 'Restore to Defaults' buttons are re-evaluated.

Apply:
a) 'original' is reinitialized to 'current'
b) 'Reset' and 'Restore to defaults' are re-evaluated.
c) If they 'current' matches 'default', remove the ini from disk.
   Otherwise, write the ini to disk.

Cancel:
a) Exit the dialog.

OK:
a) If they 'current' matches 'default', remove the ini from disk.
   Otherwise, write the ini to disk.
b) Exit the dialog.
