Fixed attribute issue

Fix for bug #40

[UCIS]

$this->attributes does get set by the svgOffset method; shouldn't the code use the local variable and check if it's actually an array? if (is_array($this->attributes) && count($this->attributes)) {

This doesn't look like the correct solution. The apparent affect on the rendered image appears to be negligible (based on some very basic testing), but the logic is a potentially significant departure. Current logic looks to be:

• if attributes have not been set at the document level then use the current SVG element initialize the document attributes/offset
• if attributes have already been set then create a group within the document for the current SVG element

With your change the logic would be:

• if the current SVG element has attributes set it as a group within the current document
• if the current SVG element does not have attributes initialize the document attributes/offset

Could your local install be an older version of php-svg-lib? As of 0.3.0 the attributes property is initialized to an array in order to avoid this issue (see 4909031bdabdc802cf49912d631690cb44b0240d).
