Fix bug reported by Travis where each url in action directory ".include" file is reported as "not canonicalized" in heritrix_out, and some end up crawled in spite of being considered included

* WorkQueueFrontier.java
    considerIncluded(CrawlURI) - call FrontierPreparer.prepare(CrawlURI) so that CrawlURI is canonicalized etc before being considered included (similar to what schedule() does)
* CrawlURI.java
    getCanonicalString(), getPolitenessDelay() - use logger instead of System.err
