minor fixes to exception reports in IncidentSvc

do not require Gaudi::Property::ValueType to be default constructible

See merge request !271

- always set color codes (even if UseColors preperty is false)
- replaced MessageSvc::initColors with specific settings in constructor
- use a slightly different reference file for python test

Removed MessageSvc::m_colMap and replaced MessageSvc::colTrans with a hidden
function.

`m_colMap` was used only twice in the code: when initialized and in
`MessageSvc::colTrans`. In any case it was equivalent to a compile time
constant.

`MessageSvc::colTrans was a method just to access `m_colMap`.

syncing MR-288 with upstream master (one conflict resolved in ForwardSchedulerSvc.cpp and added concurrency flags to AvalancheSchedulerSvc.cpp)

In order to help identify a ConditionHandle, without having to do a
lot of dcasting, and to work in both Atlas and Gaudi environments
