Summary: FormulaUtils.ionizeFormula raises exception in CDK library

Initial Comment:
Revision 2421.

When running a peak identification task against an online database, e.g. KEGG, 
the following exception is raised.

WARNING: Could not connect to KEGG Compound Database
java.lang.StringIndexOutOfBoundsException: String index out of range: 0
        at java.lang.String.charAt(String.java:686)

It looks like ionizeFormula has changed in this revision - reverting to the 
previous revision removes the bug.
