* version 1.2
* IMPORTANT: changed :command to behave like Vim's version.
Eg. An alert command specified previously as
:command AlertMe alert(args)
should now be defined as
:command AlertMe :js alert(<args>)
* IMPORTANT: changed the default keybinding to temporarily disable all
Vimperator keybindings from <C-Q> to <C-Z>

________________________________________________________________________________
Lists and defines commands. To be written - but it works similar to Vim's :command
Define a new user command. The name of the command is {cmd} and its relacement
text is {rep}. The command's attributes are {attr}. If a command with this
name already exists an error is reported unless [!] is specified, in which case
the command is redefined. Unlike Vim, the command may start with a lowercase
letter.
The replacement text {rep} is scanned for escape sequences and these are
replaced with values from the user entered command line. The resulting string
is then executed as an Ex command.
The valid escape sequences are:
`------`------------------------------------------------------------------------
<args> The command arguments exactly as supplied
<lt> A literal '<' character to allow for a literal copy of one of the escape sequences. Eg. <lt>args> will expand to a literal <args>
--------------------------------------------------------------------------------
Note: {attr} not implemented yet.
