Ricochet Refresh 3.0.12

Changes:

• Upgrade tor to 0.4.7.8
• Upgrade Zlib to 1.2.12
• Upgrade OpenSSL to 1.1.1o
• Added pluggable transport support: obfs4proxy and snowflake-clent
• Added built-in bridges for obfs4, meek-azure, and snowflake pluggable transports (parity with tor-browser's built-in bridges); custom bridges of these types should also work
• Tor daemon settings (proxy, firewall, bridges, etc) are now saved in the ricochet.json file, and SETCONF'd each run
• Improved the bootstrap+configure user
• Issues fixed:
  • #60 : Closing the first launch setup window before clicking "Connect" makes ricochet unusable
  • #65 : Make obtaining Bridges easier
• Merged/cherry-picked the following from the community (thanks!):
  • #138 : README.md: Update link
  • #140 : docs: clean and update build instructions to use CMake
  • #145 : AUR has the newer version of it
  • #149 : Upgrade deprecated Qt and protobuf functions
  • #151 : Fix race condition related to ConversationModel::clear()
  • #155 : ui: add placeholder text to Message field in ContactRequest form
