Add namespaces to Phing

[hans]

As also expressed in #86, Phing needs namespaces! Thank you, PHP 5.3, for making this possible.

First pass (a basic buildfile now works) committed in r307. More to follow, obviously, since anything but a very basic build file will almost certainly still produce PHP errors :)

seems that php 5.3 does not get namespaces

[bender]

Please don't make phing require php 5.3 features until 5.2 reaches end of life (or at least 5.3.x is the default php version for debian, ubuntu and redhat LTS releases).

I agree that support for namespaces is a great way to clean up a large and somewhat crufty php codebase, but making 5.3 a requirement for using the build system's functionality will be a major roadblock to adoption in many environments.

Valid comments - we're not even close to determining a release plan for 3.0, so there's time ;)

5.2 EOL was in July 2010, a year ago.

I am still using 5.2 on legacy systems ;-)

From my experience on other (commercial) projects - what's the value added from having to touch the entire codebase to get namespace support?

I mean, besides getting a nice way of using an autoloader ;-)? Maybe this is out of scope for this bug, but I like the Symfony loader... :)

[mrook]

Main reason: to really prevent naming clashes with other classes. Phing never used the Zend/PEAR naming conventions, so skipping that and proceeding on to namespaces seems like the logical step.

When namespaces are introduced, please make Phing PSR-0 compatible.
