Varargs for description class setters

[reckart]

Is your feature request related to a problem? Please describe. In many places in the UIMA component description classes, setters accept arrays of values. This makes code calling these setters unnecessarily verbose.

Describe the solution you'd like Where possible, the setters should be change to accept a variadic argument instead.

Although the japicmp does not seem to complain about this change, there is a source incompatibility here.

The meaning of setFoo(null); would change from set foo to null to set foo to [null]...

This change should probably only be introduced in a major version...
