deprecatedParameter moved into inputParser

The parameter deprecation methods have been moved to the
inputParser, where they are a more relevant.

Warnings regarding the deprecation of used parameters will then
happen automatically by calling the parse function.
This means that declaring a parameter as deprecated should happen
before that.
Fixed built-in function checks ACID

ACID tests for the existence of the tf and chirp function
using `exist(XX,'builtin')`. This doesn't work on MATLAB 2013b
and possibly also other versions.

Instead, the existence of the function is checked using `which`.
This causes the corresponding test cases to be run instead of skipped
