Subject: [PATCH] Added editable texts to DrawingPage

- Editable texts can be added to templates by adding a
  freecad:editable="textName" attribute to SVG <text> tags
- Added EditableTexts property (stringlist) to FeaturePage objects
- Instead of writing directly the SVG fragments to the temp file,
  they are scanned for editable texts, and if needed those are
  changed, then the final temp file is written, allowing for
  editable texts anywhere, even in FeatureView objects
- On changing the Template, editable texts are picked and
  stored in the EditableTexts property.
