PhysiBoard 3.3.0

PhysiBoard now keeps itself up to date, and Ctrl+Backspace and Alt+Backspace delete words and
lines again.

• PhysiBoard updates itself: a new release is noticed within hours, downloaded on Wi-Fi, checked
  against its published checksum and your copy's signing key, and installed while the screen is
  off. Help > Updates: install automatically, download and ask me, or off. This update itself
  installs the usual way; the ones after it arrive on their own. For silent installs, allow
  "Install unknown apps" for PhysiBoard once (Help shows the way) or pair Titan tools.
• Ctrl+Backspace deletes a word again, and a held Alt+Backspace deletes back to the start of the
  line again in Android's own text boxes (both broke in 3.1).
• Alt+Backspace can delete to the start of the line in every app: Typing > Backspace > "Alt +
  Backspace". Off by default for now.
• New installs get the screen trackpad (hold Space to move the cursor) switched on when setup
  ends with "Display over other apps" allowed, the permission it needs. Updating keeps whatever
  you had.

Install: download physiboard-3.3.0.apk and open it; it updates 3.x and 2.x in place and keeps your settings. Signing certificate SHA-256: 89a050fcb37aa14a16d77c737c70caaebdc4c7f10156f9dc8933adb3499c3261.
