Description

I've noticed that occationally vconsole and locale.conf isn't updated correctly when selecting se keymap and likely other keymaps aside of us. This PR will force an update to each file before finilizing the installation script.

Also added a "Finished" message at the end, after the "Cleaning" block.

Testing

I've run several tests and script works as expected. Installation time isn't impacted.

Additional Information

Nothing critical, but it saves the user some headache from having to manually editting the .conf files post-installation.

Updated the se keymap to sv-latin1. It was giving danish (our enemy!) keystrokes for certain letters. This resolves that so swedish users can use our dumb symbols.

I realise that 1 section of this PR could be seperated but given it so small, I thought it might be acceptable.
