fix #1260 Test launcher fixes and improvements

This commit includes the following changes:
- it fixes an issue with the form used by the launcher to request the
test classpath (the URL did not include the version number parameter
when using dev files).
- it adds the ability to change the isAmaBuild flag from the URL
(by using - or . in the second part of the version number).
- it extends the pattern of isAmaBuild URLs to include any path which
follows the /aria-templates-something pattern (instead of only
/aria-templates-dave and /aria-templates-dev).
- it adds the Aria Templates version number on the test page
