Added `lexer.colors` and `lexer.styles` and updated themes to utilize them.

This allows for a more Lua table-oriented approach to defining and using colors
and styles, instead of manually manipulating Scintilla property strings.
Themes are still backwards compatible, as the underlying mechanisms are still
in place.

 display these standard colors (which may be completely different in the end).

+#### Theme and Lexer Changes
+
+Themes and lexers have a new, optional API for defining and using colors and
+styles. Previously, all definitions and access to colors and styles was
+accomplished through `buffer.property` and `buffer.property_int`. Now it can be
+done via the `lexer.colors` and `lexer.styles` variables. For example:
+
+    -- Textadept 10
+    local property, property_int = buffer.property, buffer.property_int
+    property['color.blue'] = 0xFF0000
+    property['style.keyword'] = 'fore:$(color.blue),bold'
+    buffer.edge_colour = property_int['color.grey']
+
+    -- Textadept 11
+    local colors, styles = lexer.colors, lexer.styles
+    colors.blue = 0xFF0000
+    styles.keyword = {fore = colors.blue, bold = true}
+    view.edge_color = colors.grey
+
+Any additional settings passed `view:set_theme()` are available as global
+variables in the theme. Textadept's themes make use of `font` and `size` (the
+latter of which used to be `fontsize`) for easily configuring font and size
+per-user.
+
+Lexers can also utilize these new features. For example:
+
+    -- Textadept 10
+    lex:add_rule('custom_rule', token('custom', P('word')))
+    lex:add_style('custom', lexer.STYLE_KEYWORD .. 'italic')
+
+    -- Textadept 11
+    lex:add_rule('custom_rule', token('custom', P('word')))
+    lex:add_style('custom', lexer.styles.keyword .. {italic = true})
+
+Note that these features are optional. Themes and lexers setting property
+strings is still supported.
+
 #### Localization Changes
 
 GUI mnemonics in localization keys have been removed. For example, `_L['_New']`
