Most actions in the history module would grab the history from disk
every time the history was updated and updated the cache this way.
This commit makes these actions perform these modifications in memory
instead of unnecessarily reaching into the disk.
The 'nedb' package is unmaintained (last update was 5 years ago) and
has a couple of high severity vulnerabilities.
In addition, the use of callbacks is somewhat cumbersome for
the project's current workflow.
Therefore, I've decided to replace it with the 'nedb-promises' package,
which, internally, makes use of a maintained fork of 'nedb' and
wraps its API with Promises.
The `remote` module is deprecated and `@electron/remote` is unnecessary,
since the `ipcMain` and `ipcRenderer` can replace their functionality,
providing better performance and better security.
All other dangerous calls (mainly pulling main process constructs into
the renderer process) have also been removed.
