Remove stuff that I don't use and make config compatible with windows

Deleted:
color scheme, avy, which-key, undo-tree, org-roam

Windows compatibility:
vterm, hunspell and org now get a conditional setup based on the system
or the workplace I'm currently in.

misc:
C-w is back to default (along with backwards kill word),
ident-tabs-mode is nil by default (except of cc mode)
