0029452: Application Framework - Failed to read an Ocaf XML document with 1.#QNAN value.

Browse Source 
Method XmlObjMgt::GetReal() is improved to (a) recognize NAN and infinity written by old MSVC runtime (like 1.#QNAN and 1.#INF) and (b) detect situation when there are some trailing non-space symbols after the real value, returning False in such case.

Reading of real-valued attributes (single real, array, list) from OCAF XML format is improved to create valid attribute even if parsing of (some) members fails; warning is generated instead of error in such case.

Added test bugs caf bug29452
