Abort button on Progress is not cutomizable

[fakegermano]

The progress dialog does not have a way to customize either the text or the presence of the abort button. It should follow the pattern from the other dialogs, with customizable options using the appropriate options variable.

With this feature implemented, it is easier to utilize this package in i18n enabled projects.
