Add emin, zeh; Major updates to etr, vip; Minor to wgt, topn, ft

This is really a long overdue release.

• Document & install bu/emin

• etr gets a big update to do

  • its own looping poll when -m is given using a pretty fancy
    progress rate estimation based on recent adix histograms

  • take a kill command not signal number; -k15 -> -kkill

  • do nicer formatting & colorization of its messages which helps
    visibility if said are interleaved with monitored program output

• vip gets..

  • a bug fix for short inputs or cursoring past the end of any
    inputs & some doc tweaks.

  • new option --rev to NOT reverse input (double negative I know)

  • new option --quit to pass a string to echo on Ctrl-C and also a
    bug fix to use this when ENTER is pressed on filtered-to-empty

  • Ctrl-T now toggles case (in)sensitivity while TAB is now an alias
    for down arrow.

  • Cursoring up or down one-by-one now wraps around matched items,
    while PgDn/PgUp remain stopped by EOF & BOF.

  • Hook/plug-in/loadable module system for lazy/delayed test to show
    items. Deferred validation helps big sets of "maybe bad" entries
    with slow entry validation. The motivating use case is PWD history
    to cd into. There transiently unavailable dirs like USB drive/net
    mounts coexist with "live" dirs (& permanently gone temp dirs).
    AFAICT, though lazy loading is ancient wisdom, vip is the first
    terminal UI picker w/this ability built-in. See doc/vip.md.

  • (NOTE: Home-End seem to not register in emacs ansi-term|xterm,
    but I did not want to delay the release over that.)

• zeh added to manipulate Zsh Extended History. See zeh.md

• wgt sample exclusion file, topn can emit row slices, ft code
  matches docs for perm bits&grows --stat; Misc.code beautification.

Properly resolve (I hope) Issue#5

There was trouble compiling stripe.nim, tails.nim, and vip.nim on OSX. All now work for me now, at least on High Sierra x86_64. So, I hope #5 is fixed.

Improve `tattr` & `adorn` doc comments

adorn really isn't so needed at all anymore with the new cligen/python/pq example, but eh.. it's like 28 lines of logic.

tattr (the general need for --) can be confusing. Try to be better.

Miscellaneous non-code doc clean-ups & dependency upgrades.

Add a new small utility - `adorn`

The doc file has more details.

Minor pid2 update

to allow affinity set to user-chosen CPU for outer/shell-level loops. Plus some doc updates.-

Better `vip` error on weird /dev/tty perms/existence; Code & doc clean-ups

Subject about says it all. This is a very minor release.

Add `vip`; Make `tails` more compatible

vip is a snazzy little (v)isual (i)nteractive (p)icker that I did as a re-write of the C pick to add a dozen or so features I wanted.

tails when symlinked to head or tail now accepts the pre-POSIX / archaic -INTEGER command-line syntax.

Also:

• re-org lists in docs around rich/colorful terminal text
• Use cligen/sysUt.!! to raise exceptions
• work around a weird Nim parser bug introduced days ago

tim gets a seqNo, tslice gets factored, tails gets -C=,--Count=

Those are the 3 changes. The name of the environment variable for the tim sequence number is $TIM_SEQ. cligen nimble dep upgraded Re: tslice factoring. Finally, timing of this release was driven by use of -C in bench.sh over in procs.

Add `tslice`; Fix bug in `catz`.

That's about it. See doc/tslice.md and git log for details.

Consistencification of the rp/crp/nio q/pq universe

Not that anyone but me likely uses any of those CLI tools { especially crp ;-) }.
