build time/test jars should not be packaged with xwiki + possible bloat

xwiki already is huge with an abundance of jars.
Many jars packaged with xwiki.war are not useful during runtime and add to bloat.
Someone needs to refine the build process so build time jars are not included with runtime jars.

examples of these are:servlet-api.jar(fixed), junit-3.8.1.jar, jmock-1.0.1.jar, jtidy-8.0-20060801.131059-3-dev.jar

ehcache.jar and oscache.jar (are two caching implementations really needed??)

There maybe many others, but someone needs to go through with a fine tooth comb
ant-1.6.5.jar (maybe??)
postlet-api-1.0.jar(???)

jdom and dom4j e.g. two libs that do the same thing
