Add non-canonical mode to the sim

I want vim-esque modes to switch between schematics and commands.
This is the first step, but it makes FET_sim unsuable as it is now,
because input is not echoed back - one does not see what one enters.
Function get_next_line is not really suitable for non-canonical mode,
so an alternative (capable of parsing single char input, arrow keys
etc.) needs to be implemented.

 TODO
+implement vim-esque modes and gdb-like split screen/window for commands and schematics (TUI?)
+       implement new method of input - echoing commands, moving cursor and more
+       implement "split screen" - one for commands, one for schematics (gdb like)
+               commands screen should work just similarly to normal terminal usage
+               schematics should use vim like controls
+               each is controllable from a "mode" (at least 2 modes necessary, more may be usefull later on)
+make it possible to save schematics and use them again
+       use blocks to "condense" the schematics - similar to integrated parts
+               make blocks' schematics openable in another split screen (vim like split command?)
+                       a block opened in another screen should show current simulation state as a part of the whole simulation (or maybe a switch between free mode and bound mode?)
 make build_graph not output
 rewrite command parsing (what I've created is just ugly)
 come up with better file structure

 rewrite t_fet and t_node to store indexes insted of pointers to connected parts
        - goal shifted a bit, nodes store their ID and FETs have no use for havind ID so far
