Database changes required:
alter table history add genome_build varchar(40);
There is now a new tool ToolParameter named GenomeBuildParameter which should be useful in several existing tools.
Also took care of some other miscellaneous items.
Biomart doesn't work on the trunk yet (Before or after this commit).
axt to lav tool won't be functional until multiple datasets per history item is available on trunk - although I could
make it so that only the lav file is generated and no fasta files, in which case it wouldn't be an issue.
