find and parse manifest.json

[themasch]

If theres a manifest.json we could parse it and use the provided information to provide support in associated files.

Therefore we need to find out what files are associated with the manifest.json. Same directory & subdirs should do the job for a first version.

Information we could gather from the manifest.json

• [ ] Routes (.navTo completion)
• [ ] root view (?)
• [ ] i18n files
• [ ] Models & data sources (completions, in combination with #3 this could be a killer feature)
