store_editor: Implemented +duck and +speed buttons for menu

+speed: Negate the selected menu item
+duck: 5.0 instead of 0.5 unit changes

Behavior can be customized with the new cvar store_editor_shownegativevalues.
Various enhancements for the store_editor

* Created cvar "store_showownitems" and removed command "store_hideownitems"
* When editing a playermodel, you now get switched to thirdperson automatically and you can see your own items while editing
* Prevent reloading on items on save when another player is still editing (you are told who it is)
* Added new dependency "smlib"
store_editor: Made command executable without any arguments

No argument means self-targeting
Changed "+duck" for big unit change in store_editor to custom bind "+store_editor_bigchange"
Fix bug when saving an item

It stated that another player is still editing
