MSP430:

Browse source 
Add additional NOPs as required by hardware manual.

Microblaze:
Previously a task inherited the exception enable state from the context from which xTaskCreate() was called.  Now tasks all have exceptions enabled if they are enabled in the hardware.

Windows/GCC:
Improve the implementation of portGET_HIGHEST_PRIORITY.

Common code:
Simplify the pointer use in xQueueGenericCreate()

Demo apps: 
Remove jpg images that were used to create web pages.
Fix capitalisation issues in some demos where some header files are incldued with the wrong case, preventing building on Linux.
Remove the Microblaze demos that are using obsolete tools.
Update main_blinky for the Windows port demo to include a software timer example.
