NEW: Configurable file version prefix

Browse Source 
Numbers are often used at the end of file names in image sequences (e.g. digital photos) and the current renaming scheme can disrupt this, creating a confusing situation for the user. A configurable file version prefix should help prevent this, with a default of '-v' proposed for SS4.0.

Filename   | Old result | New result (with '-v' prefix)
-----------|------------|--------------
IMG001.jpg | IMG2.jpg   | IMG001-v2.jpg
