feat!: toggle sources/edit, many lines per source

Browse source 
Some UI tweaks (like suffixes in sliders)
Restructured data and storage: many Metrics per one Source. Each Metric
is a Line on a Panel. Fetches are handled per Source. Metrics cannot be
moved across Sources. Data points are linked to a Metric.
Also made "show sources" and "edit mode" two distinct toggles, and thus
implemented a non-edit view for sources.
Also bumped version to 0.3.0
