Please merge afer relase of 1.52 - needs more testing.
however, the examples from that thread seem to work now.

Fixed: issue #56 - import and cut, copy & paste works fine, I added a routine which increments the numbers at the end of the names, IDs will be generated automaticcaly, if the ID already exists, and the appropriate name will be increased (e.g. "mixerRight" -> "mixerRight0", "input3" -> "input4" etc.)

Improvement: import ignores lines which start with an known type but ends not with an ";"
Tidy up: deleted the "resources" folder, all static data is in the index.html file
Prepared: Looking for a solution to semi-automatic arrange imported nodes without coordinates

- fixed: clear selected nodes, works with several or all selected nodes (reason: two counting variables with the same name "i" where used in two nested loops)
- new: change node names (you can assign names to the nodes, these will be used as IDs if exported or re-imported to CPP (Arduino code)
- fixed: import merges imported nodes to existings ones, skipping nodes with the same name
- fixed: tooltips are now working, extracting the first paragraph of the HTML code
- new: nodes definition extracted to JSON file
- new: nodes help pages extracted to single HTML files
- new: form pages extracted to single HTML files
- new: asynchronous loading of JSON, help and form data, data will only be loaded when needed
- style: adapted the size of the palette, labels had been partially hidden
