Colorize text for all OTMflags in GUI

[chazshapiro]

After running the OTM, any row with a non-empty OTMflag should have colored text, and the OTMflag text of the Plan detail pane should be the same color.

Text colors: BLUE = There's an OTMflag but the exposure will be completed RED = The target will not be completed

To check if a target would be completed, check if the row has a non-empty/None OTMend value.

It looks like the RED case is already implemented but BLUE only partially.

The RED case appears to trigger on whether the OTMflag has a "-1" in it. Checking for a valid OTMend time would be more reliable.
