Overhaul the popup tips from the installer to make them translatable and
work toward popovers for all the admin and staff panel settings.

Also remove CSS properties from the style attribute that are browser
specific (like -webkit-* and such)

Previously, clients would not be able to create tickets if an internal,
required field existed on any of the forms presented to the user. Instead,
they would be stuck at permanent validation failure because there was no
data for a required field not shown.

This patch adds a feature to the form and dynamicFormEntry objects'
isValid() method to receive a callable to filter which fields' errors should
be added to the form's errors list. This allows for more complex validation
where in some cases, validation errors should not be considered on some
fields.

Fixes #45

Fixes #40

Move the cacheable code to the Http class and allow the client configuration
to be cached in the browser

Which will help fight off spammers. This should be coupled with logic that
will add some enticing fields, like 'email' and 'name' to invite bot input.
Then, on the form processing side, a spam submission can be detected and
handled differently from human submissions. This should lessen reliance on
CAPTCHA only as spam detection.

Allows the deploy script to remove files in the target that are not preset
in the current repository. This patch assumes pure stock osTicket
deployments -or- that the files deployed in the target are also present in
the local repository.
