Logo position selection retry.

Many thanks to @donmurray for pointing out the problem with bundles in #75 (as well as for the hint)! 

The bug turns out to be in “parseLogoPosition”. Given input like `mm,100,-100`, parseLogoPosition would return a string array containing `m` and `100,-100` (expected output would be `mm` and `100,-100`).

To recap…if a user does something like:

1. Open the `View>Properties` window.
2. Select a screen position other than `Lower Left`.
3. Click `OK` to close the window.
4. Reopen the `View>Properties` window.

Prior to this commit, the screen position will be reset to `Lower Left`.

This is a fix for Inquiry 1219:
