Trim most XSD types that have whitespace = collapse

[jypma]

The XSD spec says to ignore white space around decimal, boolean and
other types. However, scalaxb currently only trims URIs.

This commit adds the ability to ignore whitespace to other types, and
adds a test for this.

Fixes #554.

• I suppose the pre-generated scalaxb.scala also needs to be updated, but I couldn't find out how to re-generate it. sbt test and sbt package didn't seem to touch that file. Any hints? :-)

I feel like it's been a while regenerating that but iirc you should be able to uncomment some of the lines on:

• https://github.com/eed3si9n/scalaxb/blob/master/project/scalaxb.sbt
• https://github.com/eed3si9n/scalaxb/blob/master/project/common.scala

I've manually patched scalaxb.scala with the same changes.

Thanks!

Thanks a lot for merging!

There have been a fair few commits since the last 1.8.0 release. Would it be possible to do a bugfix release?
