upp VS appimagedl

upp instead is a simple and experimental script that can search (well) and download (quite badly) AppImages from the same sources. It is a simple bash script I've forked too, at https://github.com/ivan-hc/upp. It only needs more support and I see it as a good solution to implement AppImages from the main catalogue.

appimage is a complete utility that can download and integrate AppImages locally (the way my AppMan utility can do, but better). It also allows selection if there are multiple items. I have tested it and solved some minimal issues about dependences and some errors I got, by doing the fork of this project, at https://github.com/ivan-hc/appimagedl, I've also included some additional instructions and customized the default directories managed by this script. You can also install it as a support tool trough "AM" (recommended) and AppMan (not recommended because both can use ~/.local/bin as a $PATH). To manage the updates is recommended to install appimageupdatetool (better if through one of my two tools);
