Add standalone terminfo definition

This replaces the current definitions, which depend on the system's
'xterm-256color' terminfo definition with the `alacritty` and
`alacritty-direct` definitions.

The new definitions are completely standalone.

The default `TERM` value has been changed to be dynamically
set based on the definitions installed on the system. Alacritty will
try to use the `alacritty` definition first and fall back to
`xterm-256color` if the `alacritty` definition is not present.

@ -17,12 +17,22 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
- `buttonless` - Similar to transparent but also removed the buttons.
- Add support for changing the colors from 16 to 256 in the `indexed_colors` config section
- Add `save_to_clipboard` configuration option for copying selected text to the system clipboard
- New terminfo entry, `alacritty-direct`, that advertises 24-bit color support
### Changed
- Inverse/Selection color is now modelled after XTerm/VTE instead of URxvt to improve consistency
- First click on unfocused Alacritty windows is no longer ignored on platforms other than macOS
- Reduce memory usage significantly by only initializing part of the scrollback buffer at startup
- The `alacritty` terminfo entry no longer requires the `xterm` definition to be
present on the system
- The default `TERM` value is no longer static; the `alacritty` entry is used if
available, otherwise the `xterm-256color` entry is used instead
### Removed
- The terminfo entry `alacritty-256color`. It is replaced by the `alacritty`
entry (which also advertises 256 colors)
### Fixed

## Terminfo
The terminfo database contains entries describing the terminal
emulator's capabilities. Programs need these in order to function
properly.
Alacritty should work with the standard `xterm-256color` definition,
but to allow programs to make best use of alacritty's capabilities,
use its own terminfo definition instead.
Unless the user has set the `TERM` environment variable in the
alacritty configuration, the `alacritty` terminfo definition will be
used if it has been installed. If not, then `xterm-256color` is used
instead.
To install alacritty's terminfo entry globally:
```sh
sudo tic -e alacritty,alacritty-direct alacritty.info
```
## Configuration
Although it's possible the default configuration would work on your system,
