Provide scss values for font styling

[JosiahParry]

Per your tweet I wanted to provide the changes I made in my fork. The changes can be seen at https://github.com/JosiahParry/rsthemes/commit/70ebe49bb71a503d964717250500271e0093e1c5.

Noteably I only modified the dark theme template and hard coded some of the styling choices.

Here's how you can create your theme without needing a fork of rsthemes:

rstheme(
  "xxEmoCandyLandxx",
  theme_path = "emo-candyland.rstheme",
  theme_dark = TRUE,
  theme_flat = FALSE,
  ui_background = "#464f57",
  ui_foreground = rgb(247, 234, 148, maxColorValue = 255),
  code_string = rgb(254, 158, 229, maxColorValue = 255),
  code_value = "#DA71A3",
  code_operator = "#FF6B6B", # operators are pipes etc
  code_variable = "#FFDF7F",
  code_message = "#EB994C",
  ui_selection = "#C4832178", # highlight color
  ui_gutter_background = "#372b2b3d",
  ui_gutter_foreground = "#a36666",
  code_comment = "#C38484", # maroonish
  code_comment_background = rgb(255, 255, 255, 5, maxColorValue = 255),
  code_function = "#F77171",
  # used for rmd links or something like that
  code_reserved = rgb(255, 255, 255, 200, maxColorValue = 255),
  rstheme_terminal_colors(
    blue = "#81d497",
    red = "#ff6161",
    black_bright = "#91927d",
    magenta = "#b384bb"
  ),
  "
.ace_comment {
  background-color: $code_comment_background
}

// Function styling $code_function
.ace_keyword {
  // to do allow italics, bolds, or underline
  font-style: italic;
  color: $code_function !important;
  background-color: $code_function_background;
  &.ace_operator {
    font-style: italic;
    font-weight: bold;
  }
}"
)
