* 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.

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.
This commit implements cancelable reads, which allows Bubble Tea programs to run in succession in a single application. It also makes sure all goroutines terminate before `Program.Start()` returns.
Closes#24.
This commit also contains some refactors:
* Refactor away inputStatus type
* Refactor away program.inputIsTTY member
* Simplify how we setup and restore input when it's a TTY
This commit also consolidates the exit operations for consistency's
sake, and adds a kill() method to renderers for stopping them without
performing any final rendering.
Because they run ansyncronously, the analogous commands, when run in
a Model's Init() function, could fire after the renderer has starting
writing to output, rendering artifacts to the commandline.
v0.13.4 introduced a regression where lines weren't always cleared when
resizing the window resulting in the presence of rendering artifacts.
This commit fixes that.
The golang.org/x/crypto/ssh/terminal package is deprecated and merely a
wrapper around golang.org/x/term. Use the latter directly and avoid the
dependency on the former altogether.
* Add commands EnterAltScreen and ExitAltScreen for toggling the altscreen
* Add altscreen toggling example
* ignore .idea

The Nil Renderer essentially disables the Bubble Tea renderer sending
loggings and print statements to stdout. It can be enabled via the
ProgramOption WithoutRenderer.
