This fixes an issue with 12c54575 where the error function was always being invoked.

Based on our "docs" build target, we will have already build the docs with a clean site/ directory. After that, we generate API documentation within it, which we'd like to stick around for the deploy.

This also adjusts some API doc settings and removes various options where we were supplying default values.

Update docs and code examples for 0.2

PHPLIB-105: Remove Collection::VERSION constant

PHPLIB-83: Extend driver exceptions

PHPLIB-87: Remove manual bsonSerialize() call

Compatibility with ext-mongodb 0.6

As of PHPC-255, we cannot rewind a Cursor. PHPLIB-81 will ultimately change this by caching results; however, there is also no need to assert the iterator count here, since we're asserting the name during iteration (two CollectionInfo results would not share the same name).

Per PHPLIB-93, these classes should always have an ID, regardless of whether the driver needed to generate one.

PHPLIB-89: String getters for Database and Collection classes

This should avoid hanging test builds if mongod fails to start.

We need to account for differing service names between 2.4 and 2.6+.

nModified is not provided for legacy write ops, so we should not check for it. Once PHPC-278 is implemented, we can change these assertions to check for null exactly.
