Closes #279.

Remove hash character from make include directive

See merge request !37

`#include` is C directive that would be treated as comment in make.

Closes #273

pravopisna chyba fixed bash.md

See merge request !36

Resolves #271 #272

nova: Makefile: Use `$(MAKE)` instead of `make`

See merge request !35

This allows CLion to correctly parse `make` output and configure
its intellisense, and it's also the recommended way to recursively
invoke `make`.

Viz #260.

Děkuji Petru Pučilovi za upozornění.
