Enhancement: Consider adding a "regfdo" utility

[jbirch]

Currently, adding a new provider to the provider registry is somewhat error-prone, requiring users to manually modify the providers.xml file.

It would be nice if a tool existed that would allow users to register new providers something like:

 regfdo MyProvider.dll

Ideally, this would also test whether the provider's dependacies were met at the same time.

MapGuide includes a FdoRegUtil.exe in the FDO directory of a MapGuide installation that does exactly this.
