This release changes buffer: and user-buffer: so that the buffers they allot are properly cell-aligned, eliminating any raison d'être for aligned-buffer: and user-aligned-buffer:; this brings buffer: in line with how it functions in ANS Forth. It also fixes major performance bugs, which particularly manifest themselves under load, and bugs in the handling of tabs and Unicode in zeptoed (note that under sufficient load zeptoed does still have lag, and hence under such conditions it is inadvisable to hold down keys for extended period of times).
