Add macro support to WML.

Macros may be defined by using <M-d>

<M-d>w begins defining a windowset macro
<M-d>t begins defining a workspace macro

The next character typed is the key chord to save the macro to. The next
sequence of keys read up until the Return key is the macro value. This
macro may then be used as WML objects.

Macros are pretty primitive right now. I need to think about if it would
be worthwhile to make these macros either take arguments or add some
kind of state to WML a la sed to take a step to make the language Turing
complete, and if such a development would actually be desirable. If
anything it would be an academic exercise.

+#### Macros
+
+Remembering and using some of these key sequences can be troublesome, especially
+if that key sequences is used often. For this reason, RDE has the ability to
+record macros to reference these objects.
+
+To record a macro, type `<M-d>` then if
+  * You want to record a windowset macro, type `w`
+    1. Type the key chord to record the macro to (Ctrl+characters work well)
+    1. Type the key sequence to record and hit `<Return>`
+  * You want to record a workspace macro, type `t`
+    1. Type the key chord to record the macro to (Ctrl+characters work well)
+    1. Type the key sequence to record and hit `<Return>`
+
+Example:
+
+If one types `<M-d>w+\@..<Return>` this will record the macro `\@..` (Which
+references all windows on the current workspace except the current window) as
+`+`, so now one can type `<M-s>+_` to kill all the windows on the current
+workspace except the current window.
+
+NOTE: Recursive macros are not prohibited. Be careful!
