user-chart folder creation and demo2 documentation update

Changes:
- Added code to add user-charts folder in ~/.meep/virt-engine as part of deploy process
- Create new file to build demo2 which will copy demo2 to ~/.meep/virt-engine/

Tests:
- All UT's and cypress tests passed
- Manual testing of demo2 worked correctly

Fixed Net Char Event displays values without selecting an element

Added reset element function in store instead of updating the element on network-charac container close

Changes:
- onUpdateElement was getting called separately for type and name, so the change in type was not happening because of timing delay.
So added separate code for updating it only once.
- Removed 8081 port for MEEP_HOST in package.json since it is not required now

Test:
- All UT's and Cypress test passed
- Manually checked, the old behaviour is not observed
