installoptionalpackage needs to pull from r1alpha4

[mmadia]

Currently, installoptionalpackage is broken on r1a4 for two reasons.

1. the parsing of uname -v "hrevr1alpha4-<int>" for the variable revisionTag strips off "-<int>"
2. the r1alpha4 branch isn't pulled from.

The following code is untested, but *should* work. ... due to an issue with my local git tree and real time constraints, I can't make an actual patch tonight.

The changes in the function is to add "?h=r1alpha4" to the local url variable, which will pull the build files from the correct branch. It also makes an assumption that pulling the newest files from the r1alpha4 branch is desirable. Considering that once r1alpha4 is released to the public there will be no additional commits, IMO it is a safe assumption.

function GetBuildFile()
{
	# GetBuildFile <file>
	# Downloads files from Haiku's svn
	local buildfile="$1"
	if ! [ -f ${baseDir}/${buildfile} ] ; then
		echo "Fetching ${buildfile} ..."
		cd ${baseDir}
		local baseURL=http://cgit.haiku-os.org/haiku/plain
		#local revisionTag=`uname -v | awk '{print $1}' | sed -e 's/-.*//'`
		#	# the sed invocation above drops potential dirty markers off the
		#	# revision tag
		#local url="${baseURL}/build/jam/${buildfile}?id=${revisionTag}"
		local url="${baseURL}/build/jam/${buildfile}?h=r1alpha4"
		wget -q ${url} -O ${buildfile} \
			|| ErrorExit "...failed to download $buildfile"
	fi
}

this is the last remaining issue in R1A4... looking into now

hrev1 based on mmadia's changes

picked in hrevr1alpha4-44696

*seems* to work... mmadia, feel free to make any last minute changes though if you find a problem :D

Well, we've released, so I guess this bug should be closed...

I agree :)
