We need to allocate more memory than 128 MB in /etc/default/tomcat8

[kalxas]

After allocating 2GB, all tomcat applications work. I will commit a fix for this soon.

Fix committed:

​https://git.osgeo.org/gogs/kalxas/OSGeoLive/commit/d3d8a94aa49df07642b6c783beac4e4d01f1148d

Lets see if it works fine with 1GB of RAM, as much as our minimum requirements say ;)

Fix confirmed in nightly build 94.
