- a few esthetic change to the project browser:
 * fixed unreadeable store name when selected
 * added specific style in less file for default theme
- fixed a few icon issues following the font-awesome update
- closes #117 : settings can now be reset to defaults
 * will auto restart aswell
 * and prompt the user
- fixes #119 :
 * added autorepair for localstorage (browserstore) where the files list would accidentally get deleted (the files list, not the files)
 * the source of the issue was fixed a little way back (was a side effect in autosave)

- experimented with export to zip file of localstorage projects:
 * added jsZip lib
 * all the basic components work (fetch data, compress, parts of the ui)
 * deactivated for now, as Ui side needs a bit of cleanup, and the size of the generate zip files need to be checked
 * will likely be reused in some shape or the other in the upcomming store system refac
added g+ icon to img assets, to be loaded locally (everything should work offline)
