Description of Change

Allow Windows users to choose whether to install globally on the machine or to keep it on a user level. Solves #1172 but revert #1198 in the process.

Motivation and Context

Some users want to install Ferdium globally on the machine instead of installing only for the current user. PR #1198 changed the default behaviour and made all install per machine when it was per user previously. This PR gives the possibility to choose the location of the installation by exposing the assisted installer instead of making the installation silent. As a consequence, updating is no longer fully automatic and requires the user to validate its choice.

Possible future improvement: create/modify the nsis script to only ask for the install location on first installation, and then make the update silent by using the current installation location.
