Add build scripts for Editor

[mateofio]

Trying to build Editor is painful with respect to trying to find all the dependent Qt packages. It would be nice if we had a build script here for Editor one could run to install everything for linux and windows.

There is a buildscript for Windows Qt but it is static and takes hours to build. When you build ICU and lcf with the right flags (shared c++ runtime) this should also work with the precompiled Falls from.the Qt project. Is again a problem of static Vs shared Vs debug being incompatible 🙄

For macOS and Linux I just use the precompiled libs for now (from brew / Distribution)
