config_default.cfg reworked (#1632)
- Removed `spawnmenu_icon_precache` because it is not a valid command;
- Modified the `mp_decals` to the value of `2048` to equal the value of `r_decals` (`r_decals` gets resetted everytime you launch the game, so setting `r_decals` to `5000` will get its value back to `2048` when you relaunch the game, while `mp_decals` still with the value of `5000` because `mp_decals` it is stored in the `config.cfg` file, while `r_decals` is not, and to make both equal, here is the solution);
- Modified the value of the `sensitivity` command to the value of `6` instead of `8`.
