clean-up the jahia.properties file for the final release as there are dozen of obsolete variables in there.

IMHO Inline Editing is one of the nice Wow effect of the 6.0. However it is turn off by default. Otherwise speaking a Jahia newbie needs first to identify it in the AES menu and turn it down (80% probability that he never finds it).

So for demo purpose and especially on the hosted demo.jahia.org or on the prepackaged demo, do we rather do not want to turn on as much options as possible. Else analysts or reviewers will never find them so will never evaluate Jahia in regards of such options.
