v1.2.2

Changes:

• Add support for combinational Prefer header values. Use comma separated values for basic requests. For example: return=representation,odata.include-annotations="*".
• Add select parameter in create and updateSingleProperty functions.
• prefer parameter in basic functions can also be of Array type. So, the Prefer header value mentioned before can be written like this: ['return=representation', 'odata.include-annotations="*"'].
