Support Git branches

[tobyweston]

When it trawls the projects, it doesn't consider branch builds :(

closest I've got so far is

http://localhost:8111/guestAuth/app/rest/builds/buildType:id:radiate,branch:name:issue20

http://localhost:8111/guestAuth/app/rest/builds/?locator=buildType:id:radiate,branch:branched:true

Gives all the builds with branches but it's everything build, no grouped/reduced to unique branches. it does return <builds count="0"/> for non-branched builds.

when there are no branches, the branch attribute is missing;

<builds count="4">
<build id="4" number="4" status="SUCCESS" buildTypeId="simple_excel_main" startDate="20130728T130145+0100" href="/guestAuth/app/rest/builds/id:4" webUrl="http://localhost:8111/viewLog.html?buildId=4&buildTypeId=simple_excel_main"/>
<build id="3" number="3" status="SUCCESS" buildTypeId="simple_excel_main" startDate="20130724T190022+0100" href="/guestAuth/app/rest/builds/id:3" webUrl="http://localhost:8111/viewLog.html?buildId=3&buildTypeId=simple_excel_main"/>
<build id="2" number="2" status="FAILURE" buildTypeId="simple_excel_main" startDate="20130724T185806+0100" href="/guestAuth/app/rest/builds/id:2" webUrl="http://localhost:8111/viewLog.html?buildId=2&buildTypeId=simple_excel_main"/>
<build id="1" number="1" status="FAILURE" buildTypeId="simple_excel_main" startDate="20130724T185717+0100" href="/guestAuth/app/rest/builds/id:1" webUrl="http://localhost:8111/viewLog.html?buildId=1&buildTypeId=simple_excel_main"/>
</builds>

vs (builds with branching)

builds count="26">
<build id="37" number="33" status="SUCCESS" buildTypeId="radiate" branchName="master" defaultBranch="true" startDate="20130801T213721+0100" href="/guestAuth/app/rest/builds/id:37" webUrl="http://localhost:8111/viewLog.html?buildId=37&buildTypeId=radiate"/>
<build id="36" number="32" status="SUCCESS" buildTypeId="radiate" branchName="master" defaultBranch="true" startDate="20130801T191941+0100" href="/guestAuth/app/rest/builds/id:36" webUrl="http://localhost:8111/viewLog.html?buildId=36&buildTypeId=radiate"/>
<build id="35" number="31" status="SUCCESS" buildTypeId="radiate" branchName="master" defaultBranch="true" startDate="20130801T191321+0100" href="/guestAuth/app/rest/builds/id:35" webUrl="http://localhost:8111/viewLog.html?buildId=35&buildTypeId=radiate"/>
