Adjust the /q download command to allow downloading QuestPackages and QuestTemplates also from nested folders

[Wolf2323]

Requirements

The strict restriction to only allow downloads from the root folders QuestPackages and QuestTemplates lead to limitations that cause prescribed repository structures, that does not fit all use-cases, especially in Archives used by the Community/multiple Users.

It is required to be able to have a prefix folder, like the user who made it and a folder what project it is, before forcing the structure into the folders QuestPackages and QuestTemplates (dont limit, that this folders could contain a folder with the same name again).
With this change it would also be more usable to provide an setup with e. g. Daily Quests, based on Templates, and Download booth with one command.

TODOs

• Restructure the https://github.com/BetonQuest/Quest-Tutorials repository
  • Should we now first define the folders(path) and then the QuestPackage and QuestTemplate?
  • Should we delete the legacy default quest?
  • Any other suggestions?

New Command Structure

The Current Structure

/q download <gitHubNamespace> <ref> <type> <sourcePath> [targetPath] [recursive] [overwrite]

Use Cases:

Repository Layout

There are multiple layout choices that can be (independently) choosen:

1. Whether the quest files are committed "raw" or ordered into QuestPackages (e.g. /path/package.yml vs. /path/QuestPackages/package.yml or /quest/package.yml vs. /QuestPackages/quest/package.yml)
2. Whether the quest files are sorted into a sub-path (e.g. /path/package.yml vs. package.yml or /path/QuestPackages/quest/package.yml vs. /QuestPackages/quest/package.yml)
3. Whether the quest files are absolute or relative packages (e.g. /path/quest/package.yml vs. /path/package.yml or /QuestPackages/quest/subquest/package.yml vs. /QuestPackages/subquest/package.yml)

Selected Packages:

1. Download all packages
2. Download a subset of packages (e.g. just the quest package even though there's also a tutorial package)
3. Download a specific file (e.g. /quest/package.yml)

Target Location:

1. Same path as in repository
2. Specific path

Possible new structure

/q download <gitHubProject> <gitRef> <sourcePath> [<repoPackage>] [<localPackage>] [<type>] [recursive] [overwrite]
