A couple of POM tweaks.

- bump compiler plugin to 3.1 and fix wonky arg passing
- bump lgo4j 2.0 depend to rc2
Javadoc tweak.

1.8 javadoc now freaks out about bare < and > in Javadoc. Yay!
A bunch more Javadoc fixes.

Wow, the 1.8 javadoc tool is much stricter. For the best I suppose, though
requiring a <caption> for a <table> seems a bit excessive.

Er mah gerd. More Maven jockeying.

Apparently the "check for updated versions of plugins" plugin missed a few
spots. Also I may or may not have to specify 2.8 for maven-dependency-plugin to
avoid a bullshit CNFE during the actual release process (which conveniently
comes after Maven has committed and pushed all of its release bullshit to Git,
meaning I can't fix the release after the fact and have to make a new release).

Oh computers...
