addHtml > proper CSS inline border

[santaclaus21]

It is working:
<table style="border: 4px #FF0000 dotted;">

But it is not - this is correct W3C border syntax, additional - border width seems to be not working at all:
<table style="border: 4px dotted #FF0000;">

Seems that preg_match('/([0-9]+[^0-9]*)\s+(\#[a-fA-F0-9]+)\s+([a-z]+) is used to parse border, which definitely doesn't match CSS recommendation. This is also limited only to hex colors. Once #1669 is merged, I'll try to take a look at this. (Ping me if that has been merged and this isn't fixed.)
