WithContext lets you specify a context in which to run the Program.
This is useful if you want to cancel the execution from outside.
When a Program gets cancelled it will exit with an error
ErrProgramKilled.
Based on @knz's work in #499, but slightly supersedes this change.
A little more coupling in the resize handling, but a lot less code
& logic repetition.

* merge Adjective-Object/tea_log_renderer into standard renderer
* rename queuedMessages -> queuedMessageLines & break apart strings during message processing
* delete cursorDownBy
* += 1 -> ++ to make the linter happy
* add skipLines[] tracking back to standard renderer, and add rename skippedLines local to jumpedLines to clarify they are separate comments
* request repaint when a message is recieved
* Convert Println and Printf to commands
* Add package manager example demonstrating tea.Printf
* Use Unix instead of UnixMicro for Go 1.13 support in CI
* fix off by one in std renderer
* add Printf/Println to tea.go
* revert attempt at sequence compression + cursorUpBy

I didn't realise at the time, but the tea.Program and the renderer share
the mutex. This make the code difficult to reason about - it turns out
the program sometimes acquires the lock and then calls the
`setAltScreen` method of the renderer which in turns calls `repaint`.
That causes a deadlock as `repaint` is trying to acquire the lock too.
* feat: add OSExec helper function for running exec.Cmds
* chore: for now, un-expose WrapExecCommand
* chore: move exec struff into its own file
* chore(exec): better name for Exec func that wraps exec.Cmd (thanks, @toby)
* add: program.ReleaseTerminal and RestoreTerminal to re-use input & terminal
* chore(examples): add altscreen toggling to exec demo
* chore: put low-level altscreen stuff alongside other screen funcs

Race condition bug: Start() is called in a new gorotuine, then Send(). If the
Send happens before the msgs channel is allocated, the message is dropped.
Instead allocate the channel in the constructor, so msgs is never nil.

Sometimes it is useful to obtain the final model after the
program has finished. Add StartReturningModel() (Model, error),
so that it is possible to obtain the final model.
Make sure to keep the original Start() error function, so that
everything is backwards compatible.
