* Options block comes last to be consistent with navigator.id.get.
* fix a problem where if silent:false is specified, controller could not be found.

issue #601

Train 2011.12.01 hotfix 601 - closes #601

* Invert the meaning of the "silent" flag.
* Change channel comment location so that it is in a place that makes sense.

Adding the following API under the BrowserID.internal namespace:
* setPersistent - set the "log in automatically" flag for a site.
* get - get an assertion using the same signature/semantic meaning as navigator.id.get.

Add internal_api.js to compressed build.

issue #601

close #685

update to latest jschannel - closes #534 (innocuous console errors when messages are posted to the frame where include.js is loaded that do not have valid JSON as a payload)

run mysql tests *first* (they're more important), and if we can connect to db but browserid table doesn't exist, we still have db connectivity and can run tests

remove process.exit() from loadgen upon email addition failure.  loadgen shouldn't stop till it reaches the top.

disable http agent in http_forward - it has been capping us at five simul forwarded requests per backend process (dbwriter, keysigner)

(loadgen) optimization - re-use assertions to generate synthetic load without the client compute cost

fix regression in keysigner - ensure non-default VAR_PATH is relayed to compute processes - issue #213

tiny optimization to test running.  don't have the script that checks for db connectivity create any tables

remove the deep __heartbeat__ checks performed from browserid (the webhead), while dbwriter should ping the database to ensure health - closes #566

improve node.js version checking.  eliminate DRY violation, and use semver for robust version specification and matching.  nice yak, eh?
