Move sync state and adding functions to App.js

[zoeyfrisart]

Measurements sync, Adding mesurements and media functions should be moved to App.js

How we do it now

• Every component that needs measurements we resync the measurement.
• The Add & AddMedia Components Sync the whole measurements.
• The function that adds the data is inside the Add & AddMedia Component.

Why does this need improving.

• This request the data way more often that needed.
• We repeat the same code multiple times.
• Longer loading times.

What would we need to change.

• Move the ComponentWillMount sync state to the App.js and pass the measurements as a prop.
• Move the AddMeasurement function to App.js and pass it down as a function
• Move the AddMedia function to App.js and pass it down as a function.

What files are affected.

• add/index.js
• addMedia/index.js
• measurement/index.js
• App.js

Estimated time needed to change.

This should take a max 1-2 hours.
