Angus Gratton 678b59babf Honour values of configCPU_CLOCK_HZ & configTICK_RATE_HZ for tick rate
Fixes #147

* Can vary tick rate from 100Hz via configTICK_RATE_HZ. Note that the
  SDK binary libraries are hard-coded to assume the tick rate is 100Hz,
  so changing the tick rate may have unexpected consequences for lower
  layer WiFi behaviour (such as certain kinds of timeouts happening
  faster/slower.)

* Setting configCPU_CLOCK_HZ to 160MHz means ESP will set 160MHz during
  initialisation. Only 80MHz and 160MHz are supported.

* Timing of tasks is no longer affected by current CPU freq (whether set
  via configCPU_CLOCK_HZ or via sdk_system_update_cpu_freq().)
  Previously doubling the CPU frequency would double the tick rate.

Directories:

+ The FreeRTOS/Source directory contains the FreeRTOS source code, and contains
  its own readme file.

+ The FreeRTOS/Demo directory contains a demo application for every official
FreeRTOS port, and contains its own readme file.

+ See http://www.freertos.org/a00017.html for full details of the directory 
  structure and information on locating the files you require.

The easiest way to use FreeRTOS is to start with one of the pre-configured demo 
application projects (found in the FreeRTOS/Demo directory).  That way you will
have the correct FreeRTOS source files included, and the correct include paths
configured.  Once a demo application is building and executing you can remove
the demo application file, and start to add in your own application source
files.
