If the user launched Wizard from the menu and checked the reset
checkbox, snapshot was not taken in case no new bundles were
to be installed from resources (ie. most of the time).
Snapshot is now taken as appropriate.
A static symbol Slic3r::SEMVER is introduced, which holds
the running slicer's Semver object.
This is mainly done to make testing updater behaviour
_much_ easier. Additionaly to cleanup some questionable code
(Semver was being parsed multiple times / in multiple places
in the frontend.)
This fixes a problem where old slicer having found newer incompatible bundle
would not report an incompatibility.
The installed index check was performed too early before
bundle compatibility check. This fix moves the installed index check
to the point where a bundle would've been update (as it should be).
Removed libslic3r from the default include paths for all modules but
libslic3r. Now headers from libslic3r need to be included with an
explicit path (libslic3r/libslic3r.h etc)
Split the localization macros into I18N.{cpp,h}
