skeleton & docs (#995) 

* Documentation additions and clarifications.

Added config/boards/skeleton/ as an example and starting point for
board-specific support.

* Describe where the generated files came from.

* Minor rewording

* Delete mistakenly added emacs backups

* Added an overall description and build notes

This directory contains the source code for the RusEFI firmware.
The ideal is that typical end users should be able to use pre-built
firmware. They should not need to modify or even rebuild from the
source code for basic use, but building from the source code provides
the opportunity for optimization, supporting unexpected engine
configurations, and specialized enhancements.
TL;DR
make PROJECT_BOARD=microrusefi PROJECT_CPU=ARCH_STM32F4
Environment
Rebuilding from source code requires this firmware, a modern C/C++
compiler for embedded ARM systems, and a platform that supports 'make'
based builds.
While many compilers have the potential to work, we suggest using the
official ARM version of GCC available at launchpad.net.
Linux and MacOS systems should have the software development tools,
primarily 'make', pre-installed or readily installed. MS-Windows
requires selecting and installing a Unix-compatible system environment.
Note that the developers are volunteers, with varied motivations.
These motivations often include using leading-edge language and build
system concepts, requiring recent versions of tools. Should you
encounter build problems, review the latest version of this document.
Expected Future Changes
The firmware build is moving toward a system that separates board
features from processor features. This will require specifying both
the board type and specific processor.
The existing system evolved based on the original RusEFI boards which
used 'STM32 Discovery' development boards plugged into base boards
that held the ECU specific chips. That resulted in hard-coded
assumption about pin assignments, and associations of hardware with a
specific processor variant. That legacy is slowly being cleaned up,
but is still evident in some settings and limitations.

In TunerStudio or rusEfi console please use "Popular Vehicles" dialog to apply some of these presets. This directory contains pre-defined configurations for popular engines.
These configurations are a convenience, not a limit. Most engine types
can be manually configured.
Please do not be afraid of the content of this folder. You would NOT need your own file to start your own engine. In TunerStudio or rusEfi console use the "Popular Vehicles" dialog to
apply one of these presets.

This folder is also used by continutes integration testing suite. This folder is also used by the continuous integration testing suite.
New configurations should follow the pattern of <make>_<model>.cpp for
consistency. A future change may rename these to <make>_<engine>.cpp

This directory contains the initialization and configuration files for the
RusEFI interface to TunerStudio.
The primary contents are a set ```rusefi*.ini``` initialization files, used to
configure TunerStudio to setup and monitor a specific ECU board. These are
the only files a typical end user needs.
The ```translations``` directory contains non-English-language translations
for TunerStudio.
The initialization files are automatically generated from a combination
of input files located both in this directory and in the board-specific
directories .
```rusefi*.ini``` files are generated based on the following four inputs: ```rusefi*.ini``` files are generated based on the following four inputs:
1) ```rusefi_config.txt``` contains configuration region definition in proprietary text format. 1) ```rusefi_config.txt``` contains configuration region definition in proprietary text format.
