Yeah, should really factor out this snippet into some header file. It
is already in premac.h, but I think premac.h can't be included as such
in all the places where this copy-pasted snippet now is. Need to
experiment.

registrymodifications.xcu has been moved to the solver ( unittest/user/data )
new OOO_CONFIG_REGISTRY_EXTRA_DIR env var will be used to specify the directory 'data' will be contained in so we can override various config items.

Also added license header.

you can now use e.g. thisComponent.sheets(0).namedRanges

Ignore also MSVC warning C4686. From
http://msdn.microsoft.com/en-us/library/ae77984s%28v=VS.90%29.aspx it
seems that this is just a warning that the compiler behaviour has
changed, but that change was already in MSVC 2003. So it should be
irrelevant to us.
