Rel version 1.0.7 released.

This version of Rel -- an implementation of Date & Darwen's "Tutorial D" database language -- is a minor release featuring the following fixes and enhancements:

1. Enhancement: New built-in operator GET_UNIQUE_NUMBER returns an integer guaranteed to be unique in a given database.

2. Fix: Given TYPE POSINT IS {INTEGER CONSTRAINT INTEGER > 0}, MAX(RELATION {TUPLE {X 1}, TUPLE {X 2}}, X) failed due to a missing target. Fixed.

3. Fix: A longer default transaction timeout has been set, to reduce the likelihood of spurious timeouts in multithreaded client applications.

4. Fix: A number of bugs that prevented PRIVATE RELATION from working correctly have been fixed.
