Configure eclipse to use same source/target version as configured in maven-compiler-plugin.

With a configuration like this:

<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.3</source>
<target>1.3</target>

The following should be written to ".settings/org.eclipse.jdt.core.prefs":

org.eclipse.jdt.core.compiler.codegen.targetPlatform=1.3
org.eclipse.jdt.core.compiler.source=1.3
org.eclipse.jdt.core.compiler.compliance=1.3

We are working with a multi-module project where certain modules have a non-default source/target version because they are applets and need to be compatible with JSE 1.3. Without the above; these projects cause a mass of warnings in our eclipse workspace which shouldn't be there.
