[Therion] Inkscape import/export plugins

Thank you for writing this plug-in. I am finding it very useful for
importing survey drawings exported from other drawing programs into Therion.

Some issues I have encountered:
- Regardless of what I name my layers in inkscape, my scraps get names like
'layer1', 'layer2', etc. when I convert to th2 with the layers as scraps
option.
- If I select the line type to be 'survey' in the plug-in options, the th2
file created contains wall lines.
- When working with sketches which have not come from Therion in the first
place, you have to be careful what coordinate scale you export your inkscape
drawing from. If the coordinates are in the range 0-10 for the entire sketch
then it is not possible to zoom in very far in the therion editor to edit
the sketch, even if you scale the sketch in therion by setting survey
points. If the coordinates are in the range 0-5000 for the entire sketch
then things look fine in the sketch editor in therion, but the lox files get
created so that when you open them in Loch the scale bars are set to show
very large areas (~250km) and the actual cave model is lost somewhere in
this massive bounding box. I have found that coordinates in the range 0-500
seem to work best. So scale the entire sketch in inkscape in that coordinate
range before converting to th2.
