Allow duplicate placeholder configs if desired

[sdwr98]

Hi all,

I was very excited to see this project - we're facing the same architectural challenges that you are. One thing, though, is that in Spring MVC web applications, there is often a need to have PropertyPlaceholderConfigurers in both the root application context and the dispatcher servlet application context (because Bean Post Processors can't cross parent-child context boundaries).

This change allows the user to specify that they're ok if multiple placeholder configurers register, and will just use the config of the first one that makes it.

I'm open to feedback, but this helped us tremendously.

Thanks!
Scott

Hi @sdwr98 . It's very cool that your itch is also our itch. And thanks for the contribution. I'll take a look at your PR. The cloudbees build looks good for starters...

One comment - could you add some tests? (E.g. check it works as expected, check it fails as expected, with the various ways you can config a Spring project). Just use the existing ones in src/test as examples (they're in Spock but thats pretty easy to read).

Then I think we're good to go.

@andrewharmellaw Whoops - sorry about that. I didn't even see those hiding in the groovy folder. I've added some tests, let me know what you think.
