Removed X_IN_X redundancy

I played with the Wikipedia checker and figured that
* http://community.languagetool.org/rule/show/BIG_IN_SIZE?lang=en&subId=1
and
* http://community.languagetool.org/rule/show/X_IN_COLOR?lang=en&subId=1
are in fact redundant:

so I removed the limited X_IN_COLOR and renamed BIG_IN_SIZE which is in fact more generic to ADJECTIVE_IN_ATTRIBUTE.
