The BottomAppBar when given in the Scaffold gets hidden when the
keyboard is visible. We had hacked around that by translating its
position, however that resulted in the cursor at the bottom being hidden
when we were typing a long note.
It is not just part of the body of the scaffold.
Also converted many functions into widgets.
This adds a '+' button to the NoteEditor which allows you to add an
image from either the Gallery or Take a photo. It then accordingly adds
updates markdown.
The file is added in the same directory as the note for now.

I've tried adding a black space under the FAB, but that just reduces the
available vertical space while typing. This does reduce the usability
for small notes, as clicking on the FAB is much easier than clicking on
top-right back button or clicking the back button twice on Android.
This way most notes can immediately be edited without clicking twice -
once to switch editors and once to focus.
In the future, we should preserve the state of the editor from the last
time so that people don't need to continously switch between notes.
* We no longer have a separate editing and browsing view - This does
mean we loose the ability to quick flip between notes by swiping.
However, this is more how a note editor would behave. I do later want to
add that capability back.
* We have 2 editors for now - Markdown and Raw. By default we use the
Markdown editor which can be toggled between Preview / Edit mode.
I later want to add a rich text editor and a todo editor as well.
