Release Notes for version 2.5.2.1

This is a maintenance release. Other than introducing minor improvements in Usability/UX and a few fixes, it addresses an issue with license bindings for macOS machines.

New Features:

1. Tabular View: added new "File size" column. It carries the same piece of information as the "Bytes" column, but is shown with an easy to read format (in bytes, or KB, or MB... depending on the actual byte size).

Usability / UX:

1. Tabular View: Column "Content-Length" is now right aligned (used to be centered).
2. Tabular View: Column "Bytes" is now right aligned (used to be centered).
3. [Win] Content viewer for robots.txt: added syntax highlight support for non-standard directives "Host:" (Yandex), "Clean-param:" (Yandex), "Request-rate" (Seznam) and "Visit-time" (Seznam).
4. [Win] Uniformed Content and DOM Viewer syntax highlighting color scheme for XML syntax.
5. [Win] Uniforming Content and DOM Viewer syntax highlighting color scheme for HTML syntax.
6. [Win] HTML content syntax highlighting now also highlights script syntax (javascript source code within the HTML page).
7. [Win] Content and DOM Viewer panes now use the same font family and size.

Various:

1. [Mac] Changed the way a macOS machine "hardware signature" is computed, as it was often changed by OS updates.

Fixes:

1. [Win] Content viewer for robots.txt: fixed minor syntax highlighting issue.
2. [Win] HTML content syntax highlighting: fixes some highlighting issues for robots.txt files.
3. Minor translation fix (IT).
