Added simple filter to filter part installation

Filter filters parts by name

Updated curses port to behave more like curses

* Added redrawwin

* Added handling of null pointer to wrefresh

Moved lcmatch to game.cpp and game.h

Function lcmatch was declared too many times in too many files.

Since all of them included game.h already and including ui.h
made little sense just for lcmatch, moved it to game.*

Workaround for popup in tiles

In several places in tiles build popup didn't appear for the following
reason:

Curses port writes to back renderer but the actual screen is not updated anywhere in
cursesport.cpp. It's updated from renderer in try_update
which is called from message handling routine.

If screen was rewritten before message processed started again, then no matter
how many calls to wrefresh were done, they were not actually printed
to the screen. Only backscreen renderer changed.

Update wrefresh to update actual renderer.
Note that it's not placed inside of `if (win->draw)`.
In e.g. when popup() calls refresh mainwin->draw is false.

Refactored input_context to keep track of windows

Now after input_context corrupts screen after HELP_KEYBINDING,
it redraws windows that were assigned to it.

As result, it fixes  CleverRaven#8514, fixes CleverRaven#9835 in

* Character menu (in-game)
* Construction menu
* Character creation menu
* World creation menu
* Vehicle interaction menu
