Misc improvements including ALLOW_FILES and NEW_NOTE_NOTICE

[KTamas]

Hi,

We at Compass really like this project and are planning to deploy a version ourselves. We need a few extra configurable features that I hope will mesh well with upstream.

The changes in the PR are:

• Fix an error with file-saver being a CommonJS module
• Dockerfile linting fixes (with Hadolint)
• Add an ALLOW_FILES flag which lets the user disable file uploads
• Update @types/node
• Add a NEW_NOTE_NOTICE flag which lets you hide the notice about it being stored in the RAM etc (this would just confuse non-technical users)
• Clicking the logo should always trigger a reset, which is important after you create a note. After copying the link, it's natural to just click the logo to get back to the "homepage"

Let me know if you want any changes/improvements/if this doesn't fit well with upstream/etc.

Best
Tamas

P.S: There may be more to come but this is a good first batch.

Thats super nice! Thanks 🚀 will have a look the coming days.
One thing I already noticed: I think NEW_NOTE_NOTICE should be THEME_NEW_NOTE_NOTICE, as all the other envs are related to cosmetic changes

[cupcakearmy]

maybe we could inline the actual import, it's only one file. But I can do it in a later time

It would be nice but as far as I know, there is no way to make it one line as long as file-saver is CJS (in its current form). It seems like that package hasn't been updated for 3 years now.

I mean like removing the dependency, and just copy pasta the actual library into the code base. It's 1 file. But i'll do it in another PR :)

@cupcakearmy updated the name of the flag!
