[Tilesathome] Black tile on inkscape < 0.46 and renderstripes at default

[Ed Loach]

With the latest patch (!InkscapeV) added, and
inkscape=d:\tilesathome\inkscape\inkscape.exe in the .conf I now
get:

- Using working directory D:\TilesAtHome\tmp
! 'flock' not available. Do not run concurrent uploads
- Pngcrush version 1.6.4
- pngnq version 0.5
- Java version 1.6 is available
- rendering using or/p
- Inkscape version 0.46
- rasterizing using SVG::Rasterize::Engine::Inkscape

So it seems it was the lack of the inkscape setting in the .conf
caused the earlier message (before the == '' bit was added).
