Reporter build tracking

[ryanrdoherty]

Enables "standardized" build tracking on reporters. Thus you can now have model XML like:

          <reporter name="bed" displayName="(SRT-NEW!) BED - coordinates of sequences, configurable" scopes="results" newBuild="66"
                    implementation="org.apidb.apicommon.model.report.bed.BedGeneReporter" />

          <reporter name="sequence" displayName="(SRT-NEW!) FASTA - sequence retrieval, configurable" scopes="results" newBuild="66"
                    implementation="org.apidb.apicommon.model.report.sequence.SequenceReporter" />

which produces reporter JSON (e.g. at https://rdoherty.plasmodb.org/plasmo.rdoherty/service/record-types/transcript) like:

    {
      "isInReport":true,
      "displayName":"(SRT-NEW!) BED - coordinates of sequences, configurable",
      "name":"bed",
      "description":"(SRT-NEW!) BED - coordinates of sequences, configurable",
      "scopes":[
        "results"
      ],
      "type":"bed",
      "newBuild":"66"
    },
    {
      "isInReport":true,
      "displayName":"(SRT-NEW!) FASTA - sequence retrieval, configurable",
      "name":"sequence",
      "description":"(SRT-NEW!) FASTA - sequence retrieval, configurable",
      "scopes":[
        "results"
      ],
      "type":"sequence",
      "newBuild":"66"
    },

could u also leave description empty if there is no description (currently is being set as displayName).
