[BUGFIX] Remove inline styles from parsed blockquote tag

When passing blockquote tags trough lib.parseFunc_RTE (this
is commonly done when rendering TS objects in Fluid templates)
their attributes will be replaced with some inline styles.
I don't know what the intention of this behavior is, but it's been
like this at least since 2004. Inline styles should generally be
avoided.
I suggest to simple remove this rule.
