Do not clamp analog values to 0x3FF (ten bits), for V+ (including a Vcc sample)

[GoogleCodeExporter]

The Vcc sample, in a sample set, should not be clamped to ten bits (0x3FF). 
This change removes clamping.

Using ZigBee modules: When automatically including the supply voltage level 
(see V+,  XBee Series 2 datasheet page 135), the sample value for the Vcc pin 
(bit 7 in the analog bit field, listed on page 96) is more than ten significant 
bits. The V+ documentation suggests the useful threshold value range is 
2100-3600 mV or 0x0700-0x0c00 for standard XBee modules, and the value I 
observe from the %V command is 0xD18 (3.928v).

I would expect the analog sample value from xbee-python to be 0xD18 (3.928v), 
but instead get 0x110 (at a slightly different time) which represents 0.319v. 
Removing the clamp should allow this larger value.

Hi Mark,

Thanks for the patch; I appreciate the bug report. I will write a regression 
test for the bug and include your patch when I get a chance.
