XConfig v0.3.0

Package xconfig loads a configuration file similar to a .ini file, but with some important improvements:

The xconfig recognize bool, int, float and Strings, and also collections of values and hierarchical nested sub-config sets.
The xconfig is compatible with XDataset to inject and use in templates, database records, etc.
You can load more than one file in merge mode or replacing mode in the same config object.
You can set and get parameters at any time.
You can load the config object based on a file, but also on a string and another object; this way you can serialize, unserialize, transfer by any strem, save or load on database the object, etc.
You can also save back the config string with all its comments.
