Oops - forgot to bump cligen requirement

Some of the portability fixes require a newer cligen.

Made more portable

This now has a good chance of installing and even working on Mac OSX (but you may need to brew install libmagic for fkindc and only to do anything interesting).

Add `tim` & fix some portability bugs

See git history for some details (and recent history of https://github.com/c-blake/cligen as well). Should work on Gentoo/Arch/Ubuntu Linux now (& many others...??) and either nim-1.6 or nim-devel.

This should hopefully close #2 . Thanks for the portability debugging @laoshaw.

On FreeBSD memlat has an RNG portability problem, dirq, cbtm, and maybe pid2 should be made to compile to no-ops to not block a nimble install bu. Have not tried OSX, but releasing now since some Linux people seem interested in trying this.

Add saft; fewer warnings.

Add a utility to preserve/save file times (saft) across some command working on a file.

Cross nim compat, add 8 utilities.

Handle exit code saturation at a lower value. Fix cross-nim warnings/errors Re nimPreviewSlimSystem, add strench.sh, ww, unfold, cfold, pid2, funnel, wsz, fread, sr and batchify okpaths (for faster shell startup).

Make code consistent with nimble nim version

That's about it, really. will probably needs some >= (1,7,3) someday.

Import various from cligen/examples & more doc

Also add doc/ rationalizations for various things which had been more "exercise for the reader" style for a long time.

First tagged release

There are quite a few utilities here..some very general, some very specific.
