When installing a macro, prompt user to install a toolbar button
automatically. Fills in the details of the button using the macro's
metadata, including an icon if the __icon__ metadata variable points to
a file.
Also:
* Support XPM data for macro icon
* Support online icons
* Fix bug in macro uninstall
* Cleaned up macro code
The actual need to restart was removed by aaf4fad0c, this commit
updates the Addon Manager user interface to stop telling the user
they need to restart. Now restarting is only required for addons
that contain workbenches. Macros and pref packs to not need a
restart.
For users with git and GitPython installed, a new button is added to the
details view allowing them to change the branch they are on. Some other
minor UI changes are made to accomodate this new behavior.
Rather than manually parsing the output from the repo's host, the Addon Manager
now uses an embedded QWebEngineView to display the README data. This makes the
display more repo-location agnostic (rather than trying to parse the specific
code from GitHub, Gitlab, etc.). Special handling of known hosts is still
provided to improve the display of the page, but it is not required. Clicking a
link on the page still loads in a new system browser window, with the exception
of links to the FreeCAD wiki, which are loaded in the same browser. This is
expected to be used primarily to access traslated pages for Macros, so no
advanced web-browsing features are displayed (e.g. back buttons, history
access, etc.).
pylupdate does not extract translations when f-strings are used for the
translated text, so all f-strings are migrated to calls to format().
Several other minor translation issues are also addressed.
NOTE: This code has been run through the Black reformatter, which adds
trailing commas in many places that the stock Qt 5.x pylupdate does not
recognize. This code must be processed with the corrected pylupdate to
generate the correct translations.
