Latest IDV nightly builds require JDK 1.5

Hi All-

In case you haven't found out the hard way, the latest nightly
builds of the IDV require JDK 1.5 or higher.  The nc2.2.jar
library was build with 1.5 and we are not compiling idv.jar
with 1.5 as well.  If you try to run with 1.4, you'll get
a message like:

java.lang.UnsupportedClassVersionError: opendap/dap/parser/ParseException (Unsupported major.minor version 49.0)

       at java.lang.ClassLoader.loadClass(ClassLoader.java:235)......

There is no 1.5 specific syntax code in the source yet, but that
will be coming soon.
