BasicLink extends Inline

[Enrico Schnepel]

Hello Foppers,

I have the problem that I want to specify other inline related properties 
than color ( like text-decoration="underline" ) to basic-link. These are 
currently not supported by BasicLink. BasicLink currently extends FObjMixed.

I have changed BasicLink to "extends Inline" and removed double code. This 
results in visual properties handled by Inline and the LinkSet is set up by 
BasicLink.

I have attached the complete file.

Enrico
