Bug in v2-Check

I don’t have SVN installed here, so I’ll give you my feedback here:

In Simcast_Plugin.php:145:

$simcast_v2 = get_option('Simcast_Plugin_UseV2');

does not actually set the correct boolean value to $simcast_v2, causing the Plugin to not work with Simplecast v1 anymore.

The following modification fixes this behavior:

$simcast_v2 = get_option('Simcast_Plugin_UseV2') == "true";

It would be great if you could commit this to the code. Thank you!
