Support for including SQL queries from bundled files

[cmcgee-mac]

In case a particular query is really large or difficult to read inside your Java code, it might make sense to include the query from a separate SQL file that can be edited using a SQL editor with the syntax highlighting among other capabilities. At runtime, provided that the file is bundled in the JAR, this SQL can be loaded using the class loader. The safety from SQL injections is intact since the SQL files are totally static and the loading of their contents encapsulated in NORM.
