Eclipse-plugin: do not allow name of integration component to start with a number

[GoogleCodeExporter]

Java generally does not allow identifiers to start with a number, it is however 
not obvious that the integration component name will be used a part of a java 
package name, and the error message is nowhere near to really describe whats 
wrong and how to correct it.

---
What steps will reproduce the problem?

Use the soi-tk eclipse-plugin to create an integration component named:

061-m340ce-robust-oneway

This will fail with an obscure error message.

Building with maven at command-line makes things a bit more clear - but still 
not crisp:

cd $SOITK_GENDIR/061-m340ce-robust-oneway
mvn clean install
