Port to Windows and SQLite Extension
Migrate mdb-export changes to gmdb2

Support for octal/stip of binary
Customisation of escape string
Quoting is done according to types rather that empiric analysis of str
conversion.
Added support for sqlite
Show SQLite support in gmdb2 and manual.
Code cleanup

Enforce consistency g_malloc - g_free and malloc - free
Move var declarations on top of functions
Use macros for depreacated function attributes

This will help porting on compilers that don't support it
