Slight changes to pom.xml that eclipse needs

Eclipse shows an error with version 1.0 of maven-apt-plugin. Apparently
this is a bug in an older version, and updating to 1.1.1 seems to fix
it. More info here:

This commit also contains SvgExe stuff that I'm working on (forgot to
include it in the initial commit, whoops)
Updated apt-maven-plugin

Changed maven-apt-plugin to apt-maven-plugin to match what's here:
