We don't have to clear the screen every time, we only have to make sure
that we erase the rest of the line that used to be on the current line.
We can still optimize a bit more by finding the longest line and drawing
to that length, but using the full width is fine for now.
Plugins can now create their own commands using the `MakeCommand`
function. Plugins can also now create their own keybindings with the
`BindKey` function. See the go plugin for an example of `MakeCommand`.
This commit puts in place the ability for multiple views (splits).
This commit also removes the editor bindings so that all bindings can be
rebound by the user.
I also added some more comments
This fixes#109
These mappings include Alt+arrows and Shift+arrows and Alt+Shift+arrows
This commit also switches the version of tcell that micro uses to my
fork which supports alt, shift, and ctrl + arrows.
This commit splits "Boss mode" into to different actions. Executing
a command with Ctrl-b will now open an interactive terminal. If you
would simply like to execute a background job in the shell, press
Ctrl-e and then type `run shell-command`.
