very much work in progress on upgrade to latest GeoExplorer, needs more work
do not override constructor, but use loadConfig instead, needs more work
more complete implementation of changing config.tools
use zoom box of gxp.plugins.Zoom
preserve the alwaysZoom option
use the new beforecreateportal event to not duplicate as much code, see: https://github.com/boundlessgeo/gxp/pull/222
latest OpenGeo Suite
all js files are now in one, so clean up JSP page, also use the new paths in build.xml for ext, openlayers etc. externals
add Norwegian translations, and also modify the Norwegian JSP template
add one missing Norwegian i18n file to the buildjs config
make sure we use the latest GeoExplorer CSS, however this removes some of the local modifications which will need to be added back
start moving specific CSS out of the GeoExplorer resources (into the imr CSS)
use the same casing for both namespaces
move over more CSS
make sure we have proper i18n for the Mareano language strings
restore Mareano app logo and text
make sure the about page works again
clean up the repository
Merge remote-tracking branch 'origin/master' into master_and_upgrade

changed tabs with 4 spaces in mareano_common, moved i18n code from mareano_common to /javascript/locale/en.js and no.js - and added zoomToEmptyText value which fixes: https://github.com/Norwegian-marine-datacentre/mareano/issues/116
