Add note that uECC_VLI_NATIVE_LITTLE_ENDIAN affects key compatiblity

Add faster ARM multiplication code using UMAAL ( #69 )
...
On ARM platforms that support UMAAL, this new code should speed up curve
operations by 15-20%. There is automatic detection of UMAAL support
using compiler macros, but if it doesn't work for a given platform,
#define uECC_ARM_USE_UMAAL to 1 or 0 as desired.

fully native little endian platforms interfacing with little endian byte
streams to avoid using additional stack space and pre and post byte
reversals

uECC_HashContext => const uECC_HashContext
...
This is an important piece of "documentation" as it indicates to the
caller that a uECC_HashContext can be initialized and subsequently
used multiple times (for multiple signatures).

uECC_verify: fix prototype to indicate public_key
...
The prototype incorrectly used 'private_key' as the name
of the first argument (rather than 'public_key'). Docs and
function definition were already correctly using 'public_key'

Convert hash to int in sign/verify ( #53 )
...
Previously, callers would need to manually convert the hash value
appropriately if it was not the same length as curve_n. Now, callers
just pass in the full hash value and the length; uECC will convert
the hash as appropriate.

Updated so that private keys are always the correct length.
...
Specifically, the private key for secp160r1 is now required to be
21 bytes. Added some comments about buffer sizes.
