Woven model name fails when model name contains special characters

[Matthias Schoettle]

The COREWeaver saves the woven model (aspect) upon reuse in the copied concern folder. The name is composed of each woven models name. However, this might fail with an exception. I.e., for a segment of a URI, the Javadoc says:

"A valid path segment must be non-null and not contain any of the following characters: / ? #

Instead of using the model's name, I propose to use the model's file name, since we know already that it is valid.

Resolves #450: Changes the composition of woven aspect name to use the file name of each aspect instead.
