Fix the update message (english)

[nkesar]

Hi,

I appreciate your work. Could you please provide params to change the text title (update_title) and message (update_message) from the checkAppUpdate api.
Also please provide a button to Cancel the update in the confirm dialog. I am on version 4 (4.20).

If it's too much work, can you please at least fix "The software need to be updated" to "The software needs to be updated".

Thanks
