add autocompletion to package list

[mwarning]

The package list will autocomplete packages and only allow known packages.

[mwarning]

A source for the package list is missing.

A source for the package list is missing.

Please find a target specific index at the following URL

http://aparcar.github.io/openwrt-json/{target}/index.json

Working URL examples:

http://aparcar.github.io/openwrt-json/ath79/generic/index.json http://aparcar.github.io/openwrt-json/ath79/generic/index.json.gz

If more than just the names are needed, like a description, maintainer or latest version, please load one of the following:

http://aparcar.github.io/openwrt-json/ath79/generic/manifest.json http://aparcar.github.io/openwrt-json/ath79/generic/manifest.json.gz

[mwarning]

@aparcar the links are all dead :/

Update: Only the first two links are working now.

[aparcar]

Updated, sorry

[mwarning]

We probably need the information what packages are required (essential packages / not removeable) and which are selected already but optional and which are available.

[mwarning]

@aparcar we need to decide from where the package lists come from. What is needed is the default package list and the list of packages that can be chosen from.

I have introduced a new setting asu_packages, but it would make sense to use some sub folder of asa_url. Any preference on the sub folder path?

[aparcar]

Why not https://aparcar.github.io/openwrt-json/?

To support multiple versions I have to change the structure of openwrt-json, we could stick to the official structure of snapshots/ and releases/<version>, what do you think?

[mwarning]

ok

[mwarning]

@aparcar I have set it to config.asu_url + '/openwrt-json/' + target + '/index.json', which mightnot sit quite right with the eye..

[mwarning]

Allowing a minus in front of package names is a bit of a hassle to implement. Also, it is hard for the user to see what packages are there to be removed. Thus, it might be more elegant, to show all packages.

[mwarning]

I merge this so we can improve on it. Otherwise it will take too much time.
