No functional changes in v5.0.2.

- Updates third-party libraries, mostly used during development and packaging.
- Updates developer documentation.
- Updates the extension packaging system.

- Changed Talkie's options to open in a tab of its own rather than inside Firefox extensions page. This is due to a bug in Chromium 74 where the options would not open at all. It will require more styling in future versions, like Talkie's demo page, but also be less restricted to the size and peculiarities of the extensions page.
- Updated instructions on how to download/install additional languages/voices on Windows 10 and macOS.

- Added a demo page with several new tabs:
-- A welcome tab, which opens automatically once Talkie is installed.
-- The welcome tab should play a short sample message for any suitable voice installed.
-- A voice tab, which lists languages, dialects, voices detected on the current system (browser and operating system).
-- The voice tab has sample texts in 28 languages, displayed for matching installed languages on the current system.
-- A support tab, which lists frequently asked questions and answers.
-- Included links to additional voice installation instructions for the current operating system.

- Speak longs texts on by default in WebExtensions (Firefox) -- default off in Chrome.

- Added compact listing of some browser settings and system voices in the about tab in the options page.

- Some speed improvements:
-- Compile-time pre-render of HTML files used for the popup, the options page, as well as the demo.
-- Pre-rendered pages include critical path CSS. SVG icons and some webextensions specific CSS are still in separate CSS files.
-- Pre-rendering is done per-language and per webextension version.
-- Pre-rendered pages include known compile-time values, but not those which are browser-dependent.
-- Using reselect to memoize different filtered views of the installed voices, such as lists of languages and dialects.

- Improved graphics:
-- SVG files where possible, as before.
-- Higher resolution images (retina, @2x) where possible.

- Translations:
-- Added Bulgarian translation, making a total of 28 user interface languages/locales.
-- Updated some translation strings, and added many new strings -- especially for the support page.

- Support reading from clipboard in Talkie Premium on Chrome.
