Missing configure flags --with-slang-includes, --with-slang-libs

[humeniuc]

In mc's INSTALL file is mentioned --with-slang-includes and --with-slang-libs

`--with-slang-includes=[DIR]'
     Set path to SLANG includes [default=/usr/include]; make sense
     only if --with-screen=slang is used.

`--with-slang-libs=[DIR]'
     Set path to SLANG library [default=/usr/lib]; mke sense only
     if --with-screen=slang is used.

But when I run ./configure --prefix="$HOME/.local" --with-screen=slang --with-slang-includes="$HOME/.local/include" --with-slang-libs="$HOME/.local/lib" the following is outputed to stderr:

configure: WARNING: unrecognized options: --with-slang-includes, --with-slang-libs

Also, when I run ./configure --help| grep -i slang there is no mention of --with-slang-includes or --with-slang-libs

  --with-screen=[LIB]     Compile with screen library: slang or ncurses [slang
  SLANG_CFLAGS
              C compiler flags for SLANG, overriding pkg-config
  SLANG_LIBS  linker flags for SLANG, overriding pkg-config

These options were removed in [0a26014ca4c844ad5a157895137298fbc60f1617], but INSTALL was not cleaned up.

Fixed as [185c80ffb79ca3506c6a38a341cb724642b4120c].
