Title: 2.6

Fixed INCRBYFLOAT and HINCRBYFLOAT encoding to use scientific notation when necessary.
Removed hardcoded 17-digit precision limit, added *incrbyfloat-precision* config (Defaulting to 17). Different machines will perform double double arithmetic with different levels of precision; it therefore seems fitting to let the user decide with what precision redis should store double doubles.
