Set appropriate default instance names for the 'syntax' section

[kevinstadler]

Many core libraries (such as Hardware I/O, Video and Sound) lack @instanceName annotations on their classes, which leads to misleading 'syntax' sections of their method references already noted in processing/processing-website#397 (see e.g. movieObject.available()) which only look like:

Syntax
.methodName()

Those classes which do have an explicit @instanceName annotation (such as the Serial library) use the same instance name and description for static methods, which is also misleading (e.g. in the case of Serial.list()):

Syntax
serial.list()
Parameters
serial (Serial) any variable of type Serial

This pull request sets a non-empty default instance name which is the exact class name (for static methods) or a lower case version of the class name (for instance methods). If desired it would also be possible to add a default instance description that follows the conventions of the Processing core classes or Serial library ("any object/variable of type ...")
