Updates controlled by versions.xml in www.sleepfiles.com/oscar/versions
This removes git dependencies from everything except for version.cpp,
and removes the associated interfaces in version.h.
Since the full version string contains the branch and revision
number where applicable, the build information no longer needs
to report branch and revision separately. It also now queries
version.cpp for a more consistent and reliable build time.
Debug output of build information is also now more consistent with
less redundant code.
The full version now includes the build/git information embedded within
it as build metadata according to the Semantic Versioning 2.0.0 spec,
for example: "1.1.0-beta-1+branch-name-a1b2c3d".
Now the full version string, with all detail is always displayed
EXCEPT for release versions, in which case just the simple version
number ("1.1.0") is displayed in the primary UI.
- Main window title: simple version for release versions, full version
string otherwise
- Notifications: same as main window title
- System tray: same as main window title
- About window title: same as main window title
- About window release notes: always include full version string
- Reports: always include full version string
- Under the logo (about dialog, profile selector, new profile
window): removed, as it is largely redundant and can
interfere with the window geometry.
- Database upgrade alert: same as main window title
- Database newer alert: same as main window title
The full version string is also included within the preference and
profile .xml files, but because build metadata is ignored in version
comparisons, differences in builds will not cause any spurious
alerts. However, changes in prerelease versions will continue to
be significant, as they should be.
