Align and rationalize Build profiles

Profiles/properties/checks are inherited from Commons (see XCOMMONS-143).

In addition:

• integration-tests: run functional tests
• jetty, glassfish: run build for the specified container (jetty is the default)
• hsqldb, mysql, pgsql, derby: run build for the specified db (hsqldb is the default)
• unix, mac, windows: information for the installers and for functional tests to decide how to start XE, these profiles are automatically activated depending on the OS the build runs on
• macprofiler, winprofiler: start XE with profiling params set (they require that you set a profilePath property in your settings.xml or on the command line)
• firefox, iexplore, chrome, otherbrowser (need to define browserPath property too): run functional tests on the specified profiles, firefox being the default when not specified

To execute on CI machine: mvn clean deploy -Plegacy,integration-tests,hsqldb,jetty,firefox (to execute on HSQLDB/Jetty/Firefox, use other combinations to run the build on various environnments)
