0.4.0

Hi all,

The Plaintext plugin will soon be deprecated. This release adds a notice to the plugin whenever it loads to communicate this to users.

I have decided to deprecate this plugin for two reasons:

1. I have no time and energy to maintain it properly. The obsidian community deserves plugins that are less broken than this one.
2. There are newer plugins now, who do the same thing Plaintext do, but (in my opinion) in a better way.

There is lukasbach's Code Files plugin, which depends on an active internet connection.
There is sunxvming's VSCode Editor plugin, which also works offline. Since it works offline, this is the one I link to in the deprecation message.

I hope this release will help some users be less confused when Plaintext is gone from the community store.
