Releasenotes tntdb 1.3

Major optimization of oracle driver

The oracle driver got a major optimization. When reading multiple rows, previously each row was requested separately from OCI. Now multiple rows are fetched in a single OCI call and passed row by row to the application.

Add support for cxxtools::String (unicode string class)

Cxxtools has a string class, which supports unicode. Tntdb now has full support for it. Unicode strings can be read and written transparently.

Bugfixes and optimizations
