DATAJPA-92 - Added support for IgnoreCase keyword.

The query creation subsystem now supports using IgnoreCase when referencing String parameters, e.g.:

  findByUsernameIgnoreCase(String username);

Both 'IgnoreCase' and 'IgnoringCase' are supported. If you'd like to entirely ignore cases for all String property references add 'AllIgnoreCase' or 'AllIgnoringCase' to the query method.
