Parse attribute selectors with comma

[marcelduran]

Fixed selector parser to parse attribute selectors with/without comma properly.
Test included.

e.g.:

img[src^="data:image/png;base64,"], img[src^="data:image/jpeg;base64,"] {/*...*/}

is currently parsed as

• img[src^="data:image/png;base64
• "]
• img[src^="data:image/jpeg;base64
• "]

when the expected parsed results should be:

• img[src^="data:image/png;base64,"]
• img[src^="data:image/jpeg;base64,"]
