add mobile menu

Closes #8

Moving the .gitignore made it so that we're not ignoring the right files any more, can you please check it and commit again to remove the cached files

Since it's a draft, but you requested my review, I'm not sure how much I should review the actual functionality. Sorry if this particular comment isn't helpful and you knew about it:
The issue #8 I wrote isn't super precise, but I meant specifically that the address selection was what was the most mobile unfriendly. This problem isn't solved:

Also I think we should have the menu drawer

• not visible/actionable when on a large enough screen since it adds a click and hides the menu entries. Said differently, the menu should stay the same as it is right now on destop, and the mobile menu should be visible only on smaller screen.
• it should not push the content, it should be above it ideally, otherwise the whole content jumps all the time

[Tbaut]

Super nice, thank you so much for this. I left a couple comments, but we're super close to be golden :)

[Tbaut]

can we add the MultiProxySelection and the NetworkSelection to the mobile menu?
The Kusama deployment is imminent and while the mobile view is better without the menu, I think it won't be manageable with both the network selector and the account selector in the top bar.

[Lykhoyda]

I can do it for sure, but as a design update are pretty close we probably could wait until the final version

[Tbaut]

I think that the design update will really take a while to land, and start, so I think it's a low effort high reward thing to do.

BTW @asnaith, and also useful to you @Lykhoyda if you want to take a look at a PR and don't want to bother building the branch, you can go to the deployment page, where every commit is deployed. It's available from the main repo page as well:

And click on the view deployment. This will bring you to the deployment of the related commit. I noticed the commit hash don't match though, you should hover it, to see if it's the PR you're looking for.

Thanks for the tip about deployments @Tbaut 👍

@Lykhoyda I tested this PR out within mobile on both iOS and Android within Nova Wallet. The menu is functioning fine for me but I did notice a couple of other issues whilst viewing on mobile. I've logged them as separate issues (#105 and #106).
