Description:
Related to Bug #49113 : When the export process takes a long time, I start looking for some way to cancel it.  There is none.  Furthermore, the "Start Export" button remains active, so apparently users can kick off multiple simultaneous backups?  I don't know if this is intentional or not, but clicking it multiple times in rapid succession is good for errors.

How to repeat:
Start to export data, just keep clicking the "Start Export" button.

Suggested fix:
Disable the "Start Export" button for the duration of the process, provide ability to stop process.

Added disabling of Export/Import button during operation. Stopping the dump process will be trickier.

Added a Stop button that is enabled when Start is pressed. If you click it the export will be stopped/killed and the partial backup file will be renamed to "file.cancelled"
For import, stop will stop/kill the import process but will not do anything wrt the partially restored data.

fix confirmed. will be included in 5.2.16

An entry has been added to the 5.2.16 changelog:

There was no facility to cancel the Export to Disk process, once started, in the Administrator. Further, the Start Export button erroneously remained enabled during the export process, allowing the user to start new export processes, resulting in errors.
