Improve Import/Export capabilities

[marticliment]

General improvements in import/export in capabilities:

• Save installation options (fix [EHCANCEMENT] Better export the json file of the software list #1184)
• Save installed version (fix [ENHANCEMENT] Improve Package Export to set "Ignore Updates" & only export manually installed apps  #1393)
• Save whether the package had updates enabled or not (fix [ENHANCEMENT] Improve Package Export to set "Ignore Updates" & only export manually installed apps  #1393)

Extra:

• Add behaviour to backup packages on app launch (fix [FEATURE REQUEST] Export packages on a timer #786 )
