712ae73581 Kernel: Expose per-thread information in /proc/all 
Previously it was not possible to see what each thread in a process was
up to, or how much CPU it was consuming. This patch fixes that.

SystemMonitor and "top" now show threads instead of just processes.
"ps" is gonna need some more fixing, but it at least builds for now.

Fixes #66.

27f699ef0c AK: Rename the common integer typedefs to make it obvious what they are. 
These types can be picked up by including <AK/Types.h>:

* u8, u16, u32, u64 (unsigned)
* i8, i16, i32, i64 (signed)

2bd8118843 Kernel: Change the format of /proc/all to JSON. 
Update ProcessManager, top and WSCPUMonitor to handle the new format.

Since the kernel is not allowed to use floating-point math, we now compile
the JSON classes in AK without JsonValue::Type::Double support.
To accomodate large unsigned ints, I added a JsonValue::Type::UnsignedInt.

bc6ac1c2f2 WindowServer: Let the CPU monitor keep /proc/all open between refreshes. 
Just seek to the beginning on every iteration and start over. This avoids
a bunch of syscalls.

94a5e08faf WindowServer: Rename WSMessage* => WSEvent*. 
Since I'm on a roll here, I'll just rename WSMessageFoo to WSEventFoo now
that these inherit from CEventFoo anyway.
