Focus 0.3.4

• New features:
  • Jumping to build errors is now supported. See the default config for examples and more information (thanks @jlami for the initial implementation)
    • Use the new commands go_to_next_build_error (F8 by default) and go_to_previous_build_error (Shift-F8 by default)
    • Double-clicking the file name in the build output will also jump to the error location (provided it matched the error regex)
    • You can add Ctrl to your key combo or double-click to open on the side, as usual (when the default keybinds are used)
  • Closing an editor will now remove the corresponding file from the open files list (only if it's not modified)
  • New Handmade Hero theme (thanks @Sokus)
  • Basic JS highlighting (thanks @simonvallz)
  • It is now possible to use variables in build and run commands: %FILE%, %FILE_DIR%, %FILE_NAME%, %FILE_NAME_NO_EXTENSION%, %BUILD_WORKING_DIR%, %RUN_WORKING_DIR% (see more information in the default config)
  • New options: window_width, window_height, window_x, window_y. Can be used to configure the initial size of the editor window.
  • Focus now allows auto loading projects at startup in one of the following ways:
    • By passing a project name as a parameter: focus -project "Project Name" or focus -project path/to/project.focus-config.
    • By passing in a directory path which contains a file named .focus-config. This file will be loaded as a Focus project.
    • By launching Focus from a directory containing a file named .focus-config.
• Bug fixes:
  • C highlighting now supports identifiers which start with a UTF8 letter
• Other changes:
  • Column number shown in the footer will now count the number of characters, not the visual offset (previously it would take tab size into account)
  • Configs will be migrated to version [3]. New settings, colors and keybinds will be automatically added.
  • C highlighting has been slightly improved
