Fixed: Send to contact button too light in dark theme
Fixed: Section headers on contact detail page not visible in dark theme
Dev:
- Moved to using window.log only for all browser-context logging, with new eslint rule to prevent direct use of console.log
- Full eslintification of files in libtextsecure to take advantage of this new rule
- Removed unnecessary and too-verbose console logging
- When making thumbnail for video attachment to be sent, we generate a 100x100 preview instead of taking a full screenshot of the video
