stm32l: Correct openocd flash target name
Examples updated to use new rcc_periph_clock_enable function
Correct include path in all examples
[DOC] Updated README's for F0 and F4 examples to describe the needed board connections.
[Stylecheck] F0, F1, F4

There are remaining C99 comments.
[BUILD] Make the binaries only needed for the user

User can specify which binaries he needs on the commandline.

'make hex' will build examples with generating hex file
'make hex bin' will build hex and bin output
'make images' will build all images as in previous versions of buildsystem
'make all' or 'make' will build only elf (+ map) files

This will have huge impact on build speed.
