Fix for Load/Save mission not working (#783)

* Offline missions (with FC disconnected) are now available for load and save to file.
Supports XML file format, should be compatible enough with other software

* removed default file name

* removed code in early stage of future developments

* code style and fc buttons

* map resize handling

* fix include nwdialog and fs packages

* xml2js lib with all dependencies in a single file
