1.6.0b5	Checkmk Raw (CRE), Checkmk Enterprise (CEE), Checkmk MSP (CME)

In previous 1.6 releases the Web API did not validate the labels that could e.g. be added to hosts strictly enough. When using "python" as "request_format" this could result in a broken configuration, leading to exceptions in several places of the GUI.

The Web API now ensures the received labes are all unicode strings as Checkmk expects.
