[BUG] plugins scene need a good "revision"

[michelmno]

[BUG] why empty Plugins list in welcome page ?

use case:

• gwd started with -plugins option as suggested by wiki in https://geneweb.tuxfamily.org/wiki/gwd#Starting_the_gwd_server
  $gwfqpath/gwd -hd $gwfqpath -bd $basesfqpath -plugins -unsafe -force $gwfqpath/plugins
• but no plugins parameter in gwf file.

git blame command is reporting cid b9fbd74 as source of related change in welcome.txt

$git blame ./hd/etc/welcome.txt
b9fbd74927 (A2              2022-09-06 20:40:37 +0200 285)     %if;(plugins!="")

Multiple questions:

• As per attached image I have a Plugin information that have no provided list.
  What is the purpose of such empty list ?
• I suggest to change the test in welcome.txt
  from: %if;(plugins!="")
  to: %if;(plugins!="" & bvar.plugins!='')
• If plugins defined in gwf file, what is purpose for end user to have this list of supported plugins in the welcome page ? or is it only a debug information ?
• Is the plugins mechanism something that is still used/usefull for geneweb 7.1beta (cid 59a1e8c)?
• Would probably need to reconcile the list of plugins in wiki page to match the current list from git tree

from wiki page:
api
base64
carrousel (WIP)
cgl
easy_format
export
forum
gen
gwxjg
jingoo
no_index
piqi
sedlex
v7
v7_im
welcome (WIP)
xmlm

from git tree:
ls geneweb/plugins
cgl
export
fixbase
forum
gwxjg
jingoo
lib_show
no_index
xhtml

It is clear that the plugins scene need a good "revision".
Some plugins have been merged back into the main body (v7, v7_im, carrousel).
Some may still be usefull (cgl, forum, export, fixbase, no_index) although their effectiveness needs to be veriified.

after merge of pr #1577 in hgouraud/fix-rl branch, keep open current issue to track futur "revision" of plugins as commented above.

• cleaning half done for forum plugin cf. Forum revamp #1658

FYIO I updated the geneweb wiki https://geneweb.tuxfamily.org/w/index.php?title=plugins&type=revision&diff=4189&oldid=3997ttps://geneweb.tuxfamily.org/wiki/plugins#Geneweb_plugins
with the reduced list of plugins currently supported in source directory https://github.com/geneweb/geneweb/tree/master/plugins
More work required there to complete description of not documented plugins.
