Bristol ICE script: * adapt to take 0 days as command-line arg * provide list of locations not org_code * generate query through SQLA to avoid need for placeholders * move hl7 connection params to config file

patched genomic_xml script - error in gel_id generation; moved receiving_system & receiving_facility hl7 items to object constructor; reverted QueryLog to return if fastcgi - logging process size was killing print run - change introduced on live system 23/3/16

adapted LL::HL7 for Bristol ICE data feed; added function to suppress uninitialized warnings when using hl7d

new Gallium data script & class - will replace separate Roche & Quintiles data feeds

HL7 script; added MCHC to Hb for new units

Hb from g/cL to g/L

moved haem data calculations to convert sysmex param to real values into Worklist controller - far too slow in tt; new HL7 script & helper class
