SVGHMI: add support for "enable expressions" with arbitrary variable name assignment.
HMI tree paths can be prefixed with a variable name "@name=/MY/HMI/VAR"
Widget declarations can end with a "#" followed by a JS expression that refers to name given to variables.
Widget is disabled if expression's result is false.
Commit includes some more-or-less related generated code refactoring, that should simplify extending widget's variables attributes.

<xhtml:p><![CDATA[This example shows how you can customize build process by using 'make'.
Sometimes special steps need to be done to build entire project.
But it's not necessary to create another target in Beremiz every time you need to customize something in build process. Just use for that 'Generic' target and describe all necessary steps in Makefile.
For example, you can
- preprocess generated by Beremiz C source files,
- do some fancy source code transformation using any tools you want,
- use any compiler you want,
- call static analyzers,
- run integration tests on the project,
- upload source code to external build server,
- upload to the target and compile it there,
- flash/transfer your compiled binary to the target,
and much much more.
