* add final sqlite3 patch
* remove unused defines, join caching code with esp vfs code to reduce exported symbols and shrink final file size
* Modules should by default be disabled and in alphabetical order

This module is based on [LuaSQLite3](http://lua.sqlite.org/index.cgi/index) module developed by Tiago Dionizio and Doug Currie with contributions from Thomas Lauer, Michael Roth, and Wolfgang Oertl.
This module depens on [SQLite3](http://www.sqlite.org/) library developed by Dwayne Richard Hipp.
For instruction on how to use this module or further documentation, please, refer to [LuaSQLite3 Documentation](http://lua.sqlite.org/index.cgi/doc/tip/doc/lsqlite3.wiki).
This module is a stripped down version of SQLite, with every possible OMIT_\* configuration enable. The enabled OMIT_\* directives are available in the module's [Makefile](../../../app/sqlite3/Makefile).
The SQLite3 module vfs layer integration with NodeMCU was developed by me.
