add storage to oe template (not working) (DO NOT MERGE)

[Schwartz10]

Hey @Quazia @ottodevs and @topocount this is my first attempt at adding a default storage app to the OE template. This first commit is just to get the contracts working, and not any of the frontend / parcel stuff yet.

Important files:

changes to BaseOEApps
changes to DevTemplate.sol

storage app package.json
storage app Storage.sol

The dev template compiles (verified by navigating into the dev template directory and manually running npm run compile). But attempting to npm run start:dev from the root directory gets a VM revert:

Using network 'rpc'.

Error: VM Exception while processing transaction: revert

Before diving in any further I wanted to ask you a few Q's:

1. Is this revert from reaching the gas limit? If so, should we just install the storage app manually after running start:dev with the @aragon/cli?
2. Is continuing down this path wasted effort? (I only spent about an hour messing with it this morning, so haven't sunk much time into it at all yet).

If the revert is coming from a solidity error that I overlooked, I'm happy to keep poking around (or let me know if you see it!). Would be convenient to not have to separately install.

Thanks for any help!
