Jan Wester 3aa9cadfd8 Restore progress bar functionality
A previous fix (5f9ea3) inadvertently broke the progress bar by
converting to the wrong data type. (See issue #561 / PR #609).

While checking the code I realized the problem occurred primarily
because we weren't checking the validity of the values closer to the
source. Doing so alleviates the need to check elsewhere.

In the hope of inspiring a more systematic approach, a new uiParse()
utility function has been added to curb the further growth of toXxx()
functions that exist solely to validate user input.

There is no doubt room for improvement, both on the end of the new
uiParse() function as well as the spot where it is used. Ideally, the
data that comes out of the model should already be 'safe', but since
this is a bugfix for a bugfix I want to keep waves to a minimum.

This commit fixes issue #652.
