ATmega328PB Xplained Mini -- demo project for ATmega port. (#70)

Browse source 
* Bootstrap a demo from START. No driver is added in this commit.

* Add FreeRTOS source code to project. Remove unnecessary folder nesting.

Heap_4 is used here.

* Copy over main.c, FreeRTOSConfig.h, and regtest.{c, h}.

This commit compiles, but will need some work on timer used.

* This port has 2KB RAM. We are using 1KB for heap.

Further decreasing minimum stack size, and also use stack overflow check 1 to save some stack space.

* Preserve EEPROM set to false.

* End of the line.

* Reduce register test stack size.

32 8-bit register + 10 bytes for stack frame cost. Round up to 50.

* Adding Queue test in Integer test.

- g3 to easy debugging.
- mainCHECK_PERIOD is set to 1000 ticks. Note that this port for now use WDT as tick timer, and period is set to 15ms.
- vErrorChecks, is of highest priority. So if this task gets run before other tasks, the very first check will fail.

* Avoid false alarm.

Since we don't know in which order the tasks are scheduled, clearing any error for the first entry of vErrorChecks.

* ParTest.c to init, set, toggle onboard user LED at PB5.

* Added a task to blink onboard user LED.

Need a magic number for stack size.

* Explicitly setting timing slicing to 0.
This is to avoid unecessary context switch when multiple tasks are of the same priority.

* Add taskYIELD() at the end of the loop in each register test task.

This is to give other tasks of the same priority a chance to run, regardless of scheduling algorithm.

* minor, update comment in main.c.
