Fixed typo - chose should probably be choose

While adding a deployment, I noticed some text in the dialog said "Chose
a file".  From there, I searched for other occurences of "chose" and
where it seemed that "choose" was intended, I made the change.  This was
not an automated find/replace, so if there are errors in there, it's
totally my fault.
Added eclipse files to the ignore

Eclipse is what I had open because of a JBoss Developer Studio
evaluation.  So when I imported the console project into eclipse to make
a few changes, I noticed eclispse settings, classpath, and project files
weren't being ignored.  So I added them.
Changed Base64Encoder to javax version

Since java6 there is javax.xml.bind.DatatypeConverter for doing Base64
encoding.  This is preferrable to the previous method
(sun.misc.BASE64Encoder) because the sun.misc package is not a public
API and therefore able to change without notice or be differ between
platforms.
