Automated plugin conversion errors if angle-brackets are included in author info

[chunky]

Specifically, in my plugin, I had this:
https://github.com/chunky/gephi_graphviz/blob/master/nbproject/project.properties
Which included this line:

nbm.module.author=Gary "ChunkyKs" Briggs <chunky@icculus.org>

This caused the angle-brackets to end up nested in some other XML in the generated POM file, which maven took umbrage with.

To reproduce:

1. Fork, clone, gephi-plugins
2. Clone https://github.com/chunky/gephi_graphviz into top-level working directory of new gephi-plugins
   2a) I then deleted .git from inside gephi_graphviz clone, although I don't know if that matters
3. Run mvn org.gephi:gephi-maven-plugin:migrate

Manually editing the project.properties file to not include angle-brackets on my email fixed it
