#299 Improve output for create-function when api.name is set

[Ernst de Haan]

Currently, when "xins create-function" is executed while "api.name" is set, the following text is output:

skipping input as property api.name has already been set.

This can be confusing, especially if "create-function" is called from "create-api". Therefore I propose changing the text to read:

Adding function to API "apiname"

where "apiname" is replaced with the contents of the "api.name" property.

Yes, this output is created by Ant when the <input> task is executed with a property already set.
