VBISAM - First release

Ahhh, at last!
A 100% open source ISAM handler written in 'C' that interacts in realtime (including sharing the row-locking strategy) with the leading industry standard ISAM handler.
Better yet, it outperforms that industry standard ISAM handler by a decent margin by buffering the B+ Tree data in memory as long as possible!
A library compile time flag allows developers to finally "_BREAK_THE_2GB_BARRIER_"
(In doing so, the resultant files lose their 100% compatability with 32-bit ISAM, but gain even BETTER in-memory buffering!)

Watch this space for the addition of:
- Full transaction processing (commit / rollback)
- Virtual filesystem (Bypass the clunky Redmond FS)
- An OSS ANSI-SQL compliant RDBMS
