Clarification and markdown for boelle notes
Fixed BABYSTEPPING feature

Moved PSTR() macro to correct place which was causing the " initializer fails to determine size of '__c' " when attempting to compile with BABYSTEPPING enabled.
Added "auto fan" checks to PID_autotune

getting even with v1
Update README.md
heater.c: Limit PID I term with conditional integration.
temperature.cpp:Add PID Conditional integration on heated bed.
Configuration.m: Set PID_INTEGRAL_DRIVE_MAX from PID_MAX from BANG_MAX.

Current defaults are all 255.  If it makes sense to reduce them, they should come down together, and
be in a  PID_INTEGRAL_DRIVE_MAX <= PID_MAX <- BANG_MAX relationship.
