Applying attr for the non-availableAnim attributes

[AyanGhatak]

In redraphael, we have a list of availableAnimAttrs e.g. "stroke-opacity", ""stroke-width", etc. Apart from these other attributes are not even applied if asked to animate.

To illustrate the fact, say elem is the concerned element,

elem.animate({ path: <Array>, 'stroke-opacity': <Number>, 'stroke-dasharray': <Array>, 'stroke-linecap': <String> }, <animDuration>)

As path and 'stroke-opacity' are animatable or to say at present, we have a support for them, gets applied with an animation but for the other two attributes(namely 'stroke-dasharray' and 'stroke-linecap') do not even get applied as:

elem.attr({ 'stroke-dasharray': <Array>, 'stroke-linecap': <String> })

That is where I suggest some improvement. We do not have code for supporting animation of these attributes, thats fine, but if an user gives it should at least get applied.

This is a very required feature since the caller module would not have to take separate care for the non-animatable properties. Advantage if this is fixed properly are more separation of concern and reduced code lines.
