add option not to use pcrecpp

[k-okada]

I still have trouble on #7 and it seems something trouble if we load collada-dom vid dlopen and host program already have liked with pcre library
This PR rewrite function using pcrecpp, and confirmed it works on test code fixed in #11

intesting way of getting around this issue ;0)
using liburiparser is fine, but if you make it default, then existing users might have trouble compiling.

how about looking for liburiparser first, and then if that isn't found, falling back to using pcre?

[k-okada]

I'm not familiar with liburiparser, but it seems very stable library, it is supported from 12.04 to 15.04
http://packages.ubuntu.com/search?lang=es&keywords=liburiparser&searchon=names

My concern is I'm not confident this will get "exactly" same results as pcre provides, I have tested on test code, and it seems ok, but might be something that I missed.

[rdiankov]

i think it is a great idea to use liburiparser.
i'll look into it more to see if behavior is the same. give me a week for this ;0)

thanks, merging this it's self is ok, but to be effective on ros users,

1. update openrave launchpad
2. ask tully? to copy that launch pad deb to package.ros.org
