Changed ant build to, optionally, be more human friendly

As is, if you run the ant build, phpcs errors get written to a report file (which CI makes available via the Web interface).  It would be nice as an individual developer, though, if I could run ant and get notified of a failed build if there are phpcs errros (with those errors being output to the console so I could easily see what failed).  I changed the ant build to make this an option, with the default still being the current CI-oriented process.

Now, if the developer creates a file (~/.islandora-build.properties) that contains console-results=true, the ant build will fail if there are phpcs errors, and those errors will be displayed in the console.  Without the "console-results" setting in the local properties file, though, the ant build will behave as it did before.
