* Solve issue https://dev.yunohost.org/issues/1006
I purpose this change to improve the helper 'ynh_install_app_dependencies'.
Before this change if the dependences are not installable the install didn't fail. By these change the helper generate an error and the install stop.
* Get the error if apt fail
* Remove old change
* Add dependence choice
Add an autoremove with purge.
Some deb packages, like transmission let a lot of shit behind itself.
In case of remove then install, transmission doesn't work anymore.

- `ynh_package_remove` and `ynh_package_autoremove` were just moved up.
- Small modifications on `ynh_package_install_from_equivs`. Just added some comments and used popd instead of cd.
- Added `ynh_app_dependencies` to manage easily installation of dependencies with equivs
- And `ynh_remove_app_dependencies` to remove them.
