[PATCH v2 6/7] kernel32: Autoinitialize geographic values when launching any program.

[João Diogo Ferreira]

Autodetects the correct GeoName and GeoID based on Wine's current locale.
This should be more than satisfactory for almost everyone.

That being said, it may come in handy to bypass this in some scenarios:
  * When testing geo behaviour without wanting to change the languague;
  * Users who use a foreign language but want Wine and programs knows the
    actual country they live in;
  * Users in countries not represented by Linux or Wine locales.
    The last case is, I think, particularly important, as that'
    could cause real loss of functionality.

To opt-out:
  * Create HKCU\\Control Panel\\International\\Geo\\WineDisableAutoConfig
    * Type is REG_DWORD.
    * This key is created automatically if it doesn't yet exist.
  * Set to "1" to disable, "0" to enable.
