[Building Sakai] Mneme + 2.9.x + Java 7

[John Bush]

One of the problems is the mneme's reliance on
com.sun.image.codec.jpeg.  Profile2 addressed this by switching to
another library, see https://jira.sakaiproject.org/browse/PRFL-665.

I haven't experienced any problems in the other etudes areas you
mention as of yet, I've only just begun looking into java 7.  There
were some problems in jforum and melete that were UTF-8 related.
Those required changing the encoding using vi.
