Convert .ino -> .cpp (#2228)
- general conversion from .ino modules into a separate .cpp files - clean-up internal headers, place libraries into .h. guard .cpp with _SUPPORT flags - fix some instances of shared variables instead of public methods - tweak build system to still build a single source file via os environment variable ESPURNA_BUILD_SINGLE_SOURCE
