Latex template visual improvements

[PJBrs]

These are five patches that together improve the quality of the latex character template and that bring the information on the latex character character sheet at the same level as the fillable sheets (except the proficiencies, but neither form if perfect at this point).

The first patch creates still more room in for equipment by putting weight and carrying capacity on one line instead of two.

The second patch improves portrait handling by better resizing pictures and keeping space for text as well.

The third patch lists all classes and levels on the character sheet, instead of only the primary class and level, just as the fillable sheet.

The fourth patch adds spell components information to the spell sheets, just as the fillable sheets.

The fifth patch introduces overflow spell pages, just as the fillable sheets.

These patches hinge on a recent change in the MSavage latex character sheet that introduces automatic font downsizing to prevent text box overflow. With all this, the latex character sheet is at feature parity with the fillable forms, barring proficiencies. I do have a separate branch for improving how proficiencies are dealt with on both the latex and fillable forms.
