Fixes for gtk+3 / vte-2.91

Had to remove support for "background-tint-color" and
"dim-foreground-color" because these were removed in vte 0.38

I do not claim to understand why vte-2.91.pc = Version: 0.48.4

Running './configure --enable-gtk3'
requires a newer version of vte than the default in Artful.
Running the following commands first will force using vte-2.91

export VTE_CFLAGS=`pkg-config --cflags "vte-2.91"`
export VTE_LIBS=`pkg-config --libs "vte-2.91"`

Should fix #50
