InstantDB ignores the file extension. The ".prp" is just a convention.
It then uses java.util.Properties.load() to load the database properties and searches for
all known IDB properties, setting those that it doesn't find to suitable defaults.
The idea is that, even if you provide an empty properties files (or, as in this case, a
file full of non-properties), you still get a database.
