Updated USB HID examples with HID descriptor comments
Updated libopencm3 submodule to the newest version.
[FIX] Populate the STK_CTRL to STK_CSR change
[EXAMPLE:F0] Add basic example include
[EXAMPLE:F0] Add simple miniblink example
[EXAMPLE:F0] Add simple button example
[EXAMPLE:F0] Add simple usart example
[EXAMPLE:F0] Add usart printf example using newlib-nano
[EXAMPLE:F0] Add simple ADC example
[EXAMPLE:F0] Add example of using systick and MCO output on pin PA9.

This example is a merge of Chuck McManis's example for F4 and onnokort's system clock setting test blink example for demonstration issue, corrected in #224.

The LED in any available clock setting flashes four times per second.
[F24:CRYPTO] Add example using cryptographic module on F41x or F2x
This is a demo that uses the System Tick counter in the STM32F4
as a way of creating accurately timed delays. A simple 'msleep'
is implemented by watching the system clock to wait a certain
number of milleseconds before it returns. Its a bit more accurate
than a for loop, although it really shines when your running multiple
threads.
[tick_blink] Fixed to work with the current locm3.
[stm32l1] Add semihosting example

This is not specifically an L1 example, but it lives beside the L1 "usart"
example to show how easy it is to add semihosting support to existing code.

Tested with the by now relatively old g-a-e 2012q4 release and
OpenOcd 0.8.0-dev-00011-g70a2ffa (2013-05-14-19:41)

Port button example to WaveShare Open103R
Port fancyblink example to WaveShare Open103R
Add joystick example to WaveShare Open103R
Fix typo
Add USB<->serial loopback example to WaveShare Open103R
