#1133 Eclipse workspace relative path to ruleset.xml

[Egon]

It would be helpful, if an Eclipse-workspace relative path could be used to refer to a ruleset, e.g. that serveral Eclipse projects can refer to the same ruleset.

An absolute path is not helpful for teams and "../" to another project does not seem to work with Eclipse 4.3 (at least when a start-option like "eclipse.exe -data %RCP_WORKSPACE%" is configuring a workspace location different from the location of the projects).

A solution could be analogous to Eclipse Checkstyle configuration: http://eclipse-cs.sourceforge.net/advanced_configtypes.html
- Project Relative Configuration
- Remote Configuration

Or realtive to path variables like ${workspace_loc} and ${project_loc}, see:

This request is probably related to:
- #15 "Use URL for retrieving rulesets": https://sourceforge.net/p/pmd-eclipse/feature-requests/15/
- Discussion about "<ruleSetFile>..\pmd.ruleset.xml</ruleSetFile>": http://sourceforge.net/p/pmd-eclipse/discussion/457016/thread/1ebb7a4a

same issue here. I am working in bigger teams, right now I am duplicating all pmd rules in every project into .pmd

My bug is also related with #1051 since this was my try to configure it for the team.
Developers, please fix this!
