v0.2.0

Feature Flags

There are a couple of changes around feature flags:

• All the feature flags revolving around limited which embedded assets get
  pulled in have been ripped out. Luckily the linker is smart enough to strip
  out these unused assets which makes things a lot simpler
• There are new features to indicate which regex implementation you're using
  with syntect. Some syntaxes use features that are only provided by onig
  and not fancy-regex, so matching two-face and syntect's implementation
  keeps regex compilation infallible

Acknowledgments

Acknowledgments now includes the full listing for all syntaxes and themes
regardless of what is used. There are still individual methods to distinquish
which acknowledgments are for what though

Syntaxes

The two_face::syntax::extra() function is now
two_face::syntax::extra_no_newlines() and two_face::extra::extra_newlines()
has been added. This mirrors syntect's load_defaults_nonewlines() and
load_defaults_newlines()

Themes

two_face::theme::extra() now includes an EmbeddedLazyThemeSet. This is just
a wrapper around a LazyThemeSet tailored toward knowing all of the embedded
themes
