GT API: Provide linking to source file

[patrickrobrecht]

In a Java class (pattern/rule or match) of the generated API one should be able to jump to the gt file containing the pattern/rule with one click.

Hint: extension point org.eclipse.ui.workbench.texteditor.hyperlinkDetectors (see eMoflon/emoflon-ibex-ui#74)

Maybe use an annotation to place a link to the source file in the generated code? (to avoid to search for the gt file containing a pattern/rule of the required name)

The linking from a pattern/rule to the generated class should be easier as this follows a naming convention.

Any progress? Have you been able to reproduce? Is it clear what this issue means?
