[Hawkular-dev] logging categories

[John Mazzitelli]

I created a JIRA [1] and PR [2] so that when we build a dev build you'll get the console to show DEBUG log messages. In production mode, it stays at INFO level. I also added additional logging categories - double check that I added your component's logger categories correctly. In addition, I removed xsl:if checks and changed to xsl:choose in the .xsl.

Merge at your earliest convenience, please :)
