This combines ansi-light and ansi-dark into a single theme that works
with both light and dark backgrounds. Instead of specifying white/black,
the ansi theme uses the terminal's default foreground/background color
by setting alpha=01, i.e. #00000001. This is in addition to the alpha=00
encoding where red contains an ANSI color palette number.
Now, `--theme ansi-light` and `--theme ansi-dark` will print a
deprecation notice and use ansi instead (unless the user has a custom
theme named ansi-light or ansi-dark, which would take precedence).
Bat already has a base16 theme. The new base16-256 theme is for users
of base16-shell, who configure their terminal with a 256-color variant
of a base16 theme. These variants put some of the base16 colors in
elsewhere in the 256-color table to avoid clobbering bright color slots
(ansi codes 8 to 15) with colors that don't respect the ordinary meaning
of that slot (e.g. bright green in ordinary base16 is not green).

This changes the base16 theme back from #RRGGBB0f to #RRGGBB00,
reverting part of #934. That PR used the 0f encoding to produce ANSI
escape sequences 30-37 and 40-47 rather than 38;5 and 48;5 which require
256-color support. Unfortunately, it resulted in base16 using the wrong
colors becuase ansi_term does not support the bright variants (90-97 and
100-107) so it simply mapped them to the non-bright colors.
This PR makes combines the 00 and 0f alpha encodings into 00, and makes
them use the Color enum for the first 8 colors and Fixed otherwise. This
means the ansi-light and ansi-dark themes will work on terminals without
256-color support, and base16 will render bright colors correctly.
- New themes in `$BAT_CONFIG_DIR/themes` are now loaded *in addition* to
the default themes (they may also override).
- The `Default.tmTheme` symlink is not necessary anymore.
This relates to #172
This changes a few things:
- All syntaxes and themes are now stored (as submodules) under
assets/syntaxes and assets/themes
- The default directories for syntaxes and themes are "syntaxes"
and "themes" (used to be "syntax" and "themes")
- The "bat cache" command can now take a `--source <dir>` and
`--target <dir>` option.
- The cached files have been renamed to "themes.bin" and "syntaxes.bin"
