Title: Make PLBlockIMP drop in compatible on iOS 4 and 5

As discussed in IRC.

```
[20:22] msch: now if only someone would do the work of porting MAKVONotificationCenter to use landonf's PLBlockIMP i'd be a happy man

[20:24] landonf: msch: MAKVONotificationCenter ? that should be pretty easy. Just add pl_ to the front of its blockimp function calls. Or do something like what we did in PLWeakCompatibility to co-opt the symbol names, I guess.
```

I haven't yet had the opportunity to test on an iOS < 4.3 device.
