Empty titles in colored boxes waste space and look weird

On the left is the current rendering, whereas the rendering of my old template is shown on the right.

There is a simple fix to that. tcolorbox does this because even though the title appears to be empty it really isn't due to the inserted \setlength{\parskip}{0ex}\vphantom{/} at the beginning of every title. Just move this part to before title - a key which is only executed if there is a title.

For example, the definition for the macro \mydefinition

\newcommand{\mydefinition}[2]{
    \begin{tcolorbox}[title={\setlength{\parskip}{0ex}\vphantom{/}#1},colback=orange!10,colframe=orange!30,coltitle=black,fonttitle=\bfseries,left=1mm,right=1mm,top=1mm,bottom=1mm]
        #2
    \end{tcolorbox}
}

should become

\newcommand{\mydefinition}[2]{
    \begin{tcolorbox}[title={#1},before title={\setlength{\parskip}{0ex}\vphantom{/}},colback=orange!10,colframe=orange!30,coltitle=black,fonttitle=\bfseries,left=1mm,right=1mm,top=1mm,bottom=1mm]
        #2
    \end{tcolorbox}
}

I already added this fix to #31. In general, i would recommend using tcbset in order to avoid duplicating all those title=...,colback=... lines over and over again.

Benno, could you apply that change?

I applied the fix in 1a4c2a573633197781cc56df56abd8de9c644560.
