[latexila] Latex pp: more detailed warning message

[SÃbastien Wilmet <swilmet src gnome org>]

commit dc21c2c6857c26543f652ebdb476cc29e1d9d976

    Latex pp: more detailed warning message
    
    Here is an example of a 'latex' or 'pdflatex' warning output:
    
    Package Fancyhdr Warning: \headheight is too small (12.0pt):
     Make it at least 13.59999pt.
     We now make it that large for the rest of the document.
     This may cause the page layout to be inconsistent, however.
    
    Before this commit, the result was:
    
    \headheight is too small (12.0pt): Make it at least 13.59999pt.
    
    An important missing information is the name of the package. So now the
    result is:
    
    Fancyhdr: \headheight is too small (12.0pt): Make it at least
    13.59999pt.
