commit 9cc8d2403d89a910716c8141e8c61e4a93e49db0
Author: Ell <ell_se yahoo com>

app: factor-out common free/fg-select logic into GimpPolygonSelectTool
We currently derive GimpForegroundSelectTool from
GimpFreeSelectTool, which prevents us from making changes that are
limited to the free-select tool.
Factor out the common free-select and foreground-select logic into
a new GimpPolygonSelectTool base-class, and derive both from this
class.
