ASDK-174 downgraded to android-maven-plugin 3.8.1

After seeing a guinea-pig project fail using a-m-p 3.8.2, I looked at some issues in the 3.8.1->3.8.2 [changelog|http://code.google.com/p/maven-android-plugin/wiki/Changelog]. It sounds like they did some business with regard to apklibs that may not be working exactly as expected, as discussed here:

https://github.com/jayway/maven-android-plugin/pull/265

Seems simplest to downgrade to 3.8.1 at this point, which resolved the problems in the project in question.

Last change, I swear.
