New embed code option to hide the save button

A new embed code option called hidesave has been added to the 2.0 Recording Client. When set to 1, it hides the save button that appears when autosave (asv) is disabled (asv = 0). The default value of hidesave is 0.

Previously, when autosave was disabled, a save button was visible by default without the possibility of hiding it. Now, the save button will still be visible when disabling autosave, but it can also be hidden by setting hidesave to 1.

If both autosave (asv = 1) and hide save (hidesave = 1) are enabled, the recording still saves automatically as usual.
