 *** 0.4.1 ***

+- Modified the initialization code in order to have a dedicated idle thread in

+  the system, now the main() function behaves like a normal thread after

+  executing chSysInit() and can use all the ChibiOS/RT APIs (it was required

+  to run the idle loop in previous versions).

+  Now it is also possible to use ChibiOS/RT with a single main() thread and

+  just use it for the I/O capabilities, Virtual Timers and events. You don't

+  have to use multiple threads if you don't really need to.

 - Cleaned up the LPC2148 demo in main.c, it is now well documented and

   explains everything, I assumed too much stuff to be "obvious".

 - Added a spreadsheet in the documentation that describes the advantages

+  inlining and small changes, about 5% better scheduler performance.

 - Increased the default system-mode stack size from 128 to 256 bytes because

   some optimizations and the THUMB mode seem to use more stack space.

 - Included a Makefile in the LPC2148 demo that builds in THUMB mode.
