Added POST possibility to WebUserAgent.

Also implemented Package Verification to use POST because this hopefully fixes an
issue with some proxies and many packages.
Extended tests, named tests, improved POD to specify ArrayRef option, test for Data.
Revert "Fixed bug#9537 - DB.pm 'QueryCondition' removes backslashes (from CustomerUserID/CustomerUserLogin)."

This reverts commit 8d88b7add3d7a81223d8ec9eca1a2a54edda4eff.
Fixed HTTPS urls through proxy servers.
Added HTTPS get test.
Syntax fixes.
Added Dynamic Fields behavior feature.
