yahoo data format change - fixed

TRADABLE_DATA_CONVERSION: yahoo changed its financial data format after
the yahoo conversion algorithm was written and last updated (several years
ago).  The date used to be, e.g., 01-Feb-14; but now it's yyyy-mm-dd -
e.g., 2014-02-01.  The needed change is in converted_yahoo_line.  I kept
the old version, as converted_yahoo_line_old_format, in case the old
format shows up again.  Tested.
macl now compiles.

Got the macl client ported to the 14.05 compiler and running OK based on a
small amount of testing.  This included adding a new macl.ecf file.
14.05-related Cleanup

Removed some temporary comments introduced during the 14.05 port
and a bit of obsolete (unused or commented-out) code and some
debugging/print statements.

symbols file - removed obsolete stock symbol.
