Support XLS source type in RuleAgent
------------------------------------

                 Key: JBRULES-1680
                 URL: http://jira.jboss.com/jira/browse/JBRULES-1680
             Project: JBoss Drools
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
          Components: Drl Parser/Builder
    Affects Versions: 4.0.7
            Reporter: Michael Neale
         Assigned To: Toni Rikkola
             Fix For:  5.0.0.M2


Have had a request to support rules in xls format directly in the rule agent (we support drl). 


How to implement: 
1) look at SourcePackageProvider in drools-compiler, replicate that in the drools-decisiontable module (including the test, copy SourcePackageProviderTest for ideas on how to test it).
A decision table simply renders to drl, via  a SpreadsheetCompiler, so it should be pretty similar. 

2) Look at FileScanner.readFile() drools-core - you can see it is looking for .pkg and .drl, add .xls to this, and if .xls is found, reflectively  load the FileLoader implementation (has to use reflection as it is not in the drools-core module classpath).
