doc: add some missing info to ARM
Fix missing C++ support on Tiva-C

Would not run the global constructors and thus just
crash into the NMI handler.
components: Don't send things on default pin with DigitalWrite

Tiva-C chips crash when you go outside the expected range
on digital write. 13 must be an unlucky number.
Also fix TivaC board component not being built.
Allow pin identifiers to be a long (not just int) on Stellaris platforms
Initialize GPIO port before trying to access it

Also caused a crash on Tiva.
Add make upload-stellaris target
Make upload-stellaris target use lm4flash instead of openocd

Rename ocd target to debug-stellaris. Less hassle to setup.
doc: Update Stellaris/Tiva-C to mention lm4flash based uploading
stellaris: Fix DigitalWrite with ports other than F
stellaris: Implement serial connection

Introduces a new --baudrate option, which needs to be used for devices
which are not 9600 baud. This is the case for Tiva-C, so use:
node microflo.js runtime --serial=/dev/ttyACM0 --baudrate 115200
Rewrite MicroFloComponent
Merge branch 'master' of https://github.com/jonnor/microflo
components: Add PseudoPwmWrite
Add IO::TimerCurrentMicros(), for up to 1us resolution

Use this in PseudoPwmWrite component to improve low-dutycycle
