Applied master branch bug fixes.

- Planner was under-estimating maximum speeds through straight
junctions in certain cases. The calculations have been updated to be
more accurate.

- Strange sizeof() bug in the most recent releases. Manifested as an
alarm upon a power up even when homing was disabled. Fixed by declaring
sizeof() with struct types, rather than variable names, even though
they were validated to give the same value.

- Spindle speed zero should disable the spindle. Now fixed.

- New configuration option for inverting certain limit pins. Handy for
mixed NO and NC switch machines. See config.h for details.

// Inverts select limit pin states based on the following mask. This effects all limit pin functions,
// such as hard limits and homing. However, this is different from overall invert limits setting.
// This build option will invert only the limit pins defined here, and then the invert limits setting
// will be applied to all of them. This is useful when a user has a mixed set of limit pins with both
// normally-open(NO) and normally-closed(NC) switches installed on their machine.
// NOTE: PLEASE DO NOT USE THIS, unless you have a situation that needs it.
// #define INVERT_LIMIT_PIN_MASK ((1<<X_LIMIT_BIT)|(1<<Y_LIMIT_BIT)) // Default disabled. Uncomment to enable.
// Inverts the spindle enable pin from low-disabled/high-enabled to low-enabled/high-disabled. Useful
// for some pre-built electronic boards.
// NOTE: If VARIABLE_SPINDLE is enabled(default), this option has no effect as the PWM output and
