Also increased version of electron used.
Updated boilerplate with latest changes from https://github.com/szwacz/electron-boilerplate

Handle non ascii characters in keys with an error.

Instead of a hard to handle UnicodeEncodeError exception, check the keys and
print a human readable error. Turn more format strings into utf-8 to avoid the
exception.

Fixes #116

Updates to the ardublocklyserver package to follow naming convenctions.

This commit goes hand-in-hand with the previous. They were separated in order to ensure git correctly captured in the history the file renames instead of thinking there were deletions and new files created.

This commit on its own break ardublocklyserver, it is only pushed together with the next chronological commit.

Good foundation to expand in the future.

Also added unicode file parsing for ServerCompilersettings configparser.

Due to the continuous complications encountered when trying to freeze the python
application when it is integrated with wx widgets and the chromiun embedded
framework, Ardublockly will move its desktop deployment from using these Python
bindings to use Electron.
Electron still uses the chromiun engine, but with Node.js.
The python server application will still be packed for distribution, but using
only the modules already included in the python distribution removes all the
complications encountered so far with wx widgets and cef python.

This commit includes the following:
Move the old WX and CEF python build scripts and ci config files into the package/wxcef_build
Add Electron project files in package/electron
Update the ci config files for addition of nodejs and to build electron
Update the build scripts to only build the server python code and save in a different location
Update the packing script to accommodate all this changes
