Improve "init" command

[matz3]

Expected Behavior

When executing "ui5 init", the command should not only detect the project type but also dependencies to other libraries, components and themes. It might give hints for further steps, such as printing npm install @openui5/... to install the dependencies.

Current Behavior

"ui5 init" only detects the project type but not dependencies.

Context

• UI5 Module Version (output of ui5 --version when using the CLI): v0.2.9
