Add back expression threshold box for mRNA expression profiles

[GoogleCodeExporter]

Addd back z-score threshold for mRNA expression profiles under home page query 
section:  "Select Genomic Profiles".

This should work identically as it did before, e.g. only be displayed when a 
user selects a z-score mRNA profile.
