[finsh] Add finsh config (enabled by default)

- Modify code to adapt Arduino build process (e.g. `#include` directive)
- Map Arduino "Serial" to RT-Thread device
- Add "list_mem" to shell command
- Modify example "Blink" accordingly
- Update metadata files
- Change version to (v0.2.0)

 This is a fork of [RT-Thread](https://github.com/RT-Thread/rt-thread) project and modified for Arduino.
 
-Currently only the kernel APIs are avaiable and most of the optional components are removed for the sake of simplicity. Some of the optional components may be added back later.

+## Available Components ##
+* FinSH
+
 ## Supported Architectures ##
 * SAM (ARM Cortex-M3, Tested with Arduino Due)
 * SAMD (ARM Cortex-M0+, Tested with Arduino MKRZero)
 
 
 ## Known Issues ##
-* Native USB port is not working currently.
-
-  So for Arduino Due, please connect to host with the "Programming Port"; and for "Arduino MKRZero", please avoid using "Serial" and "rt_kprintf" (by insert `#define CONFIG_NO_CONSOLE` before `#include <rtt.h>`).
