Add the ability to link to text resource for IDE

Very basic feature, puts the url of the resource in the url for the ide
to fetch when it loads. I haven't added the ability to create these
links as it probably needs some consideration with how it fits into the
IDE.

Should work with any url that returns text but obviously has to CORS
enable since it's in the browser, of which gitlab raw content is not
which is kinda bizzare.

works with github raw content like so:
`#fetch_text_v1=https://raw.githubusercontent.com/aaevan/openscad_objects/main/fire_tablet_bottom_corner.scad`
however I would recommend url encoding it with `encodeURIComponent` in
case there are special characters in the path
`#fetch_text_v1=https%3A%2F%2Fraw.githubusercontent.com%2Faaevan%2Fopenscad_objects%2Fmain%2Ffire_tablet_bottom_corner.scad`

In the case of github, linking to raw is the safest, however it will try
and get to the raw content from the web-app url i.e. the following still
works:
`#fetch_text_v1=https://github.com/aaevan/openscad_objects/blob/main/fire_tablet_bottom_corner.scad`

Resolves #327
