some issues with symbols

[luca-penasa]

I've been adding in my fork some consistency checking for the symbols, feel free to merge with the codebase if you want (or I can provide a pull request). Here is a list the detected problems:

Most notably:

• a filename / xml name mismatch "filename 25.024: filename 25.024 and code 25.034 mismatch"
• some svg (for symbols using svgs) are pointing to the wrong path for the svg they need: those are 25.117, 25.126. This might be (part of) the problem of some thumbnails in the status table. i.e.
  
  where the missing svgs are substituted with "?".

Furthermore I suspect that when generating the pngs one should pass the full path for the svg maybe to fully solve the problem.

@luca-penasa, thanks for the name parsing control code, please go ahead with the pull request.

For the png rendering (last point), it was an issue with the SVG path at the moment of rendering - now it's fixed and the SVG patterns and symbols are rendered in the table.
