  - document `keyId` parameter
  - px (pixels) -> pt (pdf page units)
  - document --verify_level
- remove a number of documented features that were never implemented:
  - `adobeSignFieldValue` and `sigLogoAltText` from signature profiles
  - `UNDERLINE` and `STRIKETHRU` from fonts
  - `num-bytes` parameter
  - `verify_only`/`sign_only` enable states for profiles
- update mobile BKU base URL
- update pdfbox backend default to 3 in sample configurations
- consistently made boolean parsing from configuration files case permissive
- add moa verification timeout
- add support for BOLDITALIC to all base fonts, and for ITALIC to helvetica and courier
- fix a number of small quirks
  - hibernate properties are now reloaded properly
  - fix the signature block parameter key regex
  - v1 json api now correctly checks for onlinebku/mobilebku being enabled
  - pdfbox 2 module correctly compares for integer equality regardless of cached boxed ints
  - test operationcountwatcher no longer sometimes breaks due to spring context differences
