Added new method ResourceDB::matchItems() which returns a list of item
which somehow match the given list of keywords.
Furthermore renamed ItemList to ItemHashMap to better reflect actual
container type.
Additionally some coding style improvements.

Added itemByHash() method to ResourceDB class allowing safe access to
an item identified with an according hash. If there's no item associated
with the hash, NULL is being returned.

Naming classes like ResourcesItem or ResourcesDatabase is bad style,
therefore rename all classes and files to be Resource*.
