Extract seller names from artwork titles

[BergFulton]

Currently, seller names are jammed in the same line as the artwork title. A script needs to be written to help extract the seller name away from the artists and put that name in to the seller field.

The syntax should be pretty easy, as it is usually something like

Firstname Lastname. 21. Painting Title
So parsing on the period after the character, but before the first digit, would probably do it.
