Update README with `kext-dev-mode` warning and updated installer link

v0.2.0

0.1.0

cool new shit:
- dramatically improved stability
  - it hasnt crashed on me yet. <= 0.0.3 crashed every ten minutes
- no configuration—when the app launches, it detects the computers default output device and uses that for output automatically
  - on quit, WavTap resets the system default device/volume to the state it was in when WavTap launched
  - simplified menu: "Record" and "Quit"
- new app icon
- status bar icon becomes red while recording (immediate visual feedback, yo)
- status bar icon inverts color on click (idiomatic to osx, dogg)
- records in 16–bit by default instead of 32
  - near-future goal is to respect your Audio MIDI Setup bit depth settings
- removed every last reference to "Cycling74" and "Soundflower"
  - shouldnt collide with Soundflower anymore
- code love:
  - now uses ARC
  - removed all deprecated method calls
  - now compiles with zero warnings

breaking changes:
- theres no longer a way to change the "Record" hotkey
  - and there wont be for a bit (until theres a proper Preferences menu)
- theres no longer a way to change WavTaps output device
  - instead: quit the app, set the default output device in Audio MIDI Setup, and relaunch WavTap
- it now crashes if the system output devices sample rate changes
  - prior to 0.1.0 it just made a high-pitched squelching noise (e.g. fax machine vomit)
    - arguably this is an improvement
