[hibernate-dev] upgrade to gradle 1.0-m9

[Strong Liu]

I have pushed my changes [1]

some notes here:

* this upgrade does not resolve the GRADLE-2169 issue, my build still hangs (but with "-i" option, it disappears, needs to dig more )
* the gradle-jdocbook change doesn't compatible with previous gradle release (there is a gradle class renamed)
* I have to change manual's xml to use namespace instead of the old dtd, jdocbook plugin can't resolve those locally, that's why it takes so long to finish [2]
* I haven't created pull request yet, just want to hear feedback first
