[xwiki-devs] [proposal] upgrade web-gwt to gwt 1.4

Hi developers! I'd like to upgrade the web-gwt module to gwt 1.4, as in the dedicated branch https://svn.xwiki.org/svnroot/xwiki/xwiki-platform/web/branches/xwiki-web-gw... . A stable upgrade will be finalized tomorrow, although there will still remain a couple of appearance issues to be solved until the xwiki-web 1.4 milestone release. WDYT?
