Remove mimetype of libreoffice-calc

This mimetype affects icon resolution for apps with identical
   name. Methodology:

cd /usr/share/icons/Chicago95
for word in $( find . -path '*apps*' ! -type d -printf '%f\n' | awk -F'.' '!x[$1]++{print $1}' | sort ) ; do find mimes -name "${word}.???" ; done | sort -t'/' -k3

mv libreoffice-calc.png x-office-spreadsheet.png # which is one of its symlinks!
for word in $( find . -xtype l -printf '%l %f\n' | awk '$1 ~ /libreoffice-calc/{print $2}' ) ; do echo ln -sf x-office-spreadsheet.png ${word} ; done
