Release 0.7.11 "Rest" - Refine interactive stack, graphics in help

This release is a refinement minor release. The primary focus is the interactive stack, which now lets you edit items, sort either according to memory representation or by value, display information about objects, and jump directly to a given stack level using digits.

The simple random number generator implemented in 0.7.10 was replaced with an additive congruential random number generator (ACORN), which can be configured in number of bits and number of iterations. A side effect is that there is now regression testing for single-variable statistics.

The history feature was also improved by automatically enabling the EditMenu when selecting history, and then having the (unshifted) word left and word right commands automatically cycle through history if used at beginning or end of the editing buffer.
