Fix for CiviCRM 4.4: the template.php.tpl is now template.php.template (we keep backwards-compat for older versions).

added civicrm-encryptdb function, but will need to be refactored using CRM/Utils/DBEncrypter.php to avoid duplication.

some refactoring around the code to check whether the upgrade needs to be done. Trying to solve issues around the 4.0 -> 4.1 upgrade (need to declare an upgrade variable to avoid civicrm checking its civicrm_settings table).

Issue #1775346 : while testing platform/site install, do not use provision's test functions because of defined paths (and to avoid future issues if provision_tests change)

Issue #1775346 : while testing platform/site install, do not use dots in the platform names, since provision/hosting gets confused.

Issue #1696730 : removing the use of provision_post_deploy() because it's causing too many issues, compared to the relatively low inconvenience of running civicrm-update-db in a post_verify().

In verify/deploy: check the result of provision_civicrm_verify_common() before continuing, since it does checks to see whether we are running on a very old version of civicrm
