Fix bug: mistaken istarts_with with find_first_of
Change select_{set,iterator,statement} code to allow: null iterator (end), const initialized, without flag; statement execution from tuple
Feature: select() SQL query generation (first steps, simple select all queries with orders and limits, sqlite/mysql only for now)
Make get<> in entities public, also add entity_tuple_t typedef
Database array implementation: bind any select statement to XML renderer, and it will be lazy evaluated when needed
Bump xmlrenderer version
