### new option to filter added repository-references when assembling a p2-repository

The repository references automatically added to a assembled p2-repository (via `tycho-p2-repository-plugin`'s `addIUTargetRepositoryReferences` or `addPomRepositoryReferences`)
can now be filtered by their location using exclusion and inclusion patterns and therefore allows more fine-grained control which references are added.
```xml
<plugin>
<groupId>org.eclipse.tycho</groupId>
<artifactId>tycho-p2-repository-plugin</artifactId>
<version>${tycho-version}</version>
<configuration>
... other configuration options ...
<repositoryReferenceFilter>
<exclude>
<location>https://foo.bar.org/hidden/**</location>
<location>https://foo.bar.org/secret/**</location>
</exclude>
<include>%regex[http(s)?:\/\/foo\.bar\.org\/.*]</include>
</repositoryReferenceFilter>
</configuration>
</plugin>

```
