v1.1.2 release

This release brings several bugfixes:

• KiKit no longer crashes on projects without an absolute path
• formatting string {time24} was fixed
• several documentation strings were made more accurate
• a bug in arc reconstruction was fixed
• component placement files never output more than two decimal places as more places are not accepted by most fab houses
• we removed dependency on zip executable (so all commands now work well on Windows)
• KiKit can correctly handle schematic sub-sheets that used to be top-level sheets.

With these bugfixes the following options were added:

• --debug flag for the fab command
• we added an option to disable arc reconstruction in a separate command.

All users are encouraged to upgrade.
