Undrawn balance model now includes date customer was paid.
chgs print dealers not to have customer acct id again
lcavailment bank and ccy fields removed.
added clarec details to lcavailment
strip clarec details of leading/trailing white space
flexcube id is no longer unique in lcavailment cos of clarec
lcavailment - strip lc number of white space.
lcavailment unmatched none value bug fixed

The bug emanated from the fact that I ever needed to create
from unmatched recons and never via lcavailment admin. So the code
to avail assumed that I will always have an unmatched primary key.
This clarec thing is messing up my code base.
chgs and ibd int got clarec details.
ibd int write posting now excludes umatched.
ibd int write posting ccy corrected to currency
lcavail should warning if no narration.
Raise error if credit item tagged negotiated in lcavail.
Raise error if float credit item tagged negotiated in lcavail.
Raise error if decimal credit item tagged negotiated in lcavail.
Lcavail availed custom date bank ppty changed to swift_bic.

This is one more reason I need automated test.
ibdint, lcavail and postentry get tests for updating post_date.
Remove postentry.entrycontra.ref cos clarec made it redundant.
lcavail get stmt/flex and dr/cr flags to control negotiated objects.
dont allow multiple availment in lcavail app.
