version bump for release
NXT analog sensor fixes
* change NXT light sensor scaling and data type
* fix light sensor ambient mode not working.
* fix NXT-ANALOG-1 mode not working
Eliminated hold_mode, it's now part of brake_mode.
Added brake_modes attribute
framebuffer does not need to alloc memory on every update

also reduced mmap buffer size
add fuse and ext4 file systems
use dma for framebuffer memory in st7586fb.c

This fixes an issue when writing to the framebuffer using mmap. Since Linux
memory is cached, we were getting artifacts displaying on the screen when
writing to the memory mapped file because the deferred io function was being
called long before the kernel memory was actually updated. DMA memory is not
cached, so this eliminates the problem.
Make EV3 "back" button backspace instead of ESC
[legoev3_battery] attempt to add "couloumb counting"

upowerd needs the energy_now or charge_now attribute in order to display
the "rate" (current engery consumption in Watts).
