Optional whitespace trimming of keys and values

[sandrock]

Consider the following data strings:

Key1=Value...1;Key2=Valu  ;Key3=X
Key1=Value1;   Key2=Value2;Key3=X

The user may use whitespaces to align keys and values. Consider adding three 4 properties to the parser in order to trim these characters.

bool TrimKeyLeft
bool TrimKeyRight
bool TrimValueLeft
bool TrimValueRight
