In this version :
* EXISTS
* consistency check in INSERT...SELECT
* DISTINCT, ALL
* transactions

The transaction stuff is pellicular. It simply maps to vendor calls. I 
am hesitating a bit, either make a common interface for the most common 
operations (like execute) directly in each backend (aside with 
vendor-specifc calls) or put them in a separate wrapper or even decide 
that it's not in the scope.

There's more redesign in the select from which I think I can get an 
elegant implementation of vendor-specific features (like LIMIT). The 
idea is to pass all the data in a fusion map, allowing vendor specific 
parts of the statement to slip their own data inside it. In fact this 
also is how DISTINCT works.

I dropped the composition of lists via chained calls to operator (). 
It's all preprocessor-based now. The () chain system was limited by 
FUSION_MAX_VECTOR_SIZE anyway.

I have installed MySQL on my computer. I am still accessing it via ODBC 
but I'll probably start the native support soon.

Yesterday I tried to upload and just when I pushed the upload button the 
vault server crashed. I suspect that it was my upload that triggered it.
