added Invisible to interface and parse method

[hklages]

Add property "Invisible" to member definition (interface, method)

Description

In case of a stereo pair one player gets "Invisible", property "Invisible", value is '1' Players being "visible" don't have that property.

2 things:

• I am not sure what Typescript does in case the property does not exist
• The test is 1 (same as for MicEnabled) althought debug says it is of type string '1'
