Ionic conversion

As discussed before, we'd want to convert the application to ionic before it's too late. I did some research on it and it should be accepting regular web stuff so we want to "port" the application with as little changes as possible at first.

The general approach would be the following:

• Start the empty template with react ionic, make sure to turn it from TS to JS for an easier time
• Start adding the libraries we use, but some are already covered in ionic, such as router and react (instead of preact)
• Copy over our content using the same file structure as what we had instead of the ionic template, make sure IonApp is the top level component and router stuff works through ionic, make sure to wrap "pages" in IonContent, other components can be changed to their ionic counterparts later if we want to

Might be missing something, might run into unexpected problems, comment on issue or message me if so.
