Passive SearchBar

Some of the creative mode tabs(such as the vanilla "Search Items" tab) come with a search bar. The search bar is always focused when the tab is opened, so it recognizes most of the keyboard input as characters and puts them into the search bar, which is annoying for players (including the author >_<) who are used to using the E key to close the tabs.

This mod makes the search bar no longer autofocus when a tab is opened, and lose its focus when the player clicks outside the search bar.

The 1.12.2 version of this mod requires MixinBooter.
