[TYPO3-templavoila] mapping type 'RANGE' misses when having multiple CSS classes

[lukas.rueegg [pixworx multimedia]]

and as a remark: the following code does not work with RANGE:
<div class="col_left col_border">
</div>
<div class="col_right_small">
</div>
<div class="col_left col_border">
</div>
<div class="col_right_small">
</div>

but this IS working (only one class in the first and third DIV):

<div class="col_left-col_border">
</div>
<div class="col_right_small">
</div>
<div class="col_left-col_border">
</div>
<div class="col_right_small">
</div>

thanks, lukas.
