Clean up source file main methods

[cipherboy]

A number of files outside of the tests package have main methods. These include:

org/mozilla/jss/ssl/SSLClient.java:384:  public static void main(String argv[])  throws Exception
org/mozilla/jss/ssl/SSLTest.java:17:    public static void main(String[] args) {
org/mozilla/jss/ssl/SSLServer.java:264:    public static void main(String argv[]) throws Exception
org/mozilla/jss/util/Base64InputStream.java:225:    public static void main(String args[]) throws Exception {

org/mozilla/jss/netscape/security/x509/CRLDistributionPoint.java:254:    public static void main(String args[]) throws GeneralNamesException, IOException, InvalidBERException {
org/mozilla/jss/netscape/security/x509/IssuingDistributionPointExtension.java:359:    public static void main(String args[]) {
org/mozilla/jss/netscape/security/x509/CRLDistributionPointsExtension.java:237:    public static void main(String args[]) {
org/mozilla/jss/netscape/security/x509/IssuingDistributionPoint.java:274:    public static void main(String args[]) {
org/mozilla/jss/netscape/security/x509/FreshestCRLExtension.java:250:    public static void main(String args[]) {
org/mozilla/jss/provider/javax/crypto/JSSSecretKeyFactorySpi.java:275:    public static void main(String args[]) {

It'd be good to review these and either add them to the tests package as a unit test or remove them if they're unnecessary. Command line utilities should perhaps be migrated to a separate package or source file.
