#1 Fixes compilation under Java 1.5

[Dan]

Two files have a variable called "enum". They are:
src/butterfly/xmlview/gui/NewFileWizard.java
src/butterfly/xmlview/help/ZvonDocumentation.java

"enum" is a reserved word in Java 1.5, so ButterflyXML
doesn't compile. There's a compiler switch to force
compilation anyway but it's not enabled by default.

I changed those two files.
