* For reprap (really Marlin) or Repetier flavors and a toolchange retract, produce G10 S1 instead of G10.
Also refactored comments (were getting eaten by fw retract)
* Fixed tests to check for correct retract gcode output.
* Better reference to scalar.
* Added config checks for if fw tool retracts are in place and firmware is repetier/marlin, disable the advanced option.
* Disable z lift if firmware retraction is enabled.
* With gcode comments on, indicates which extruder Slic3r thinks it is retracting/unretracting.
* Deploy PRs to branches/ subdir.
* wrong path to util
* added PR number to file name
* check for appveyor pr variable
* also use branches if pushing a branch on windows
* also use branches if pushing a branch on unix
* wrong or operator on powershell
* only decrypt if the key is available
* Use script instead of explicit command
* Don't deploy if the keyfile is missing/empty.
* Don't deploy if key is not available.
* Don't decrypt appveyor key if no secret
* wrong name
* Fix the logic and a typo
* linux packaging script should be functional now (from travis)
* Updated travis to build with distribution
* Moved cache management to script.
* Add perlbrew download
* Point to my server and use the correct perlbrew path.
* added bintray encrypted link
* used right script name
* fixed deploy path and used correct deploy
* Updated to use TRAVIS_COMMIT env variable
* updating deployment for travis
* oops, inverted logic
* Cleanup of files, renamed make_par to make_archive.
Factored out some functions to common/util.sh
* replaced slic3r dir with current dir (not script dir)
* ensured PAR::Packer is installed.
* added -v to install
* can't mix globbing and shell replacement in the same thing.
* adding some debug code, setting sudo: false
* factored out get_app_name
* added set version to utils
* prototype appimage
* cache perlbrew, added ./ to WD in make_archive
* added more noise
* sudo-false takes twice as long to build for some stupid reason.
* make unzip quiet.
* run ldd bundle to see output
* quiet down tar, set ld library path
