Lusci - A Scite with many Lua extensions

Hello All. Thankyou for accepting my request to share this with the group.
Over years of customising Scite, I have accumulated around 5-10 Kloc of lua 
script extensions. So I have made a project of fixing and fitting them into 
a pre-configured install which others can test and fork, without too many 
bumps, hopefully.

At the core 'Lusci' includes a module which efficiently checks any 
keypresses and runs functions which have been registered to their key 
combinations.
For example here is a function which removes trailing whitespace:
```
function deleterightwhite() -- uses core function 'filtertext' 
  filtertext( 
    function(c) return c:gsub("[^%S\r\n]+$", "") end 
   ,"sa" -- filter ("s")election or ("a")ll or ("w")ord or ("l")ine
  )
  return true -- true disables normal action for key
end
```
And then one line can register it to a key combo:
```
lusci_command("del trailing whitespace|deleterightwhite|ctrl+alt+t")
```
That particular hotkey is not included in the install, yet it would be
easy to drop in. There are many others to use or modify. Lusci's default 
keymap and features are currently documented at some length at the bottom 
of the project Readme.md

Lusci makes Scites output pane more terminal like, with a simple path 
prompt,
system commands, and 'lusci commands' and ability to run lua snippets.
For example a command called 'pallet,' instantly flips theme luminosity 
or visually adjusts theme contrast brightness etc.
All lusci commands can be abbreviated to first two letters and are followed 
by a comma to distinguish them from terminal commands.

ctrl+tab, cycles through most recently dwelled buffers which is refined to 
work nicely
ctrl+`, brings up a sorted file switcher modal
Lusci remembers all files ever opened and has commands to quickly find, 
list and reopen files. On Linux, protected files can be saved with entering 
sudo password, and sudo commands can be run too.
Lusci has commands to quickly search or replace terms in files and 
directories and list them within the output pane, quite like vanilla scite, 
just without modals and with some possible refinements.
Buffers can be transparently encrypted, with a cypher implementation which 
is  probably not secure but is non-trivial to recover.
And there are some more features and curiosities. 
...
Lusci configs for Windows and Linux are hosted at :
https://codeberg.org/lusci/lusci

The Windows config is missing a couple of features, but I can add them soon 
if there is any interest.
I hope this post has not been too long. I have briefly set up a little 
board for possible Lusci chatter too.

Many Thanks,
Andrew
