Add checkbox state to fix issue

[PushpenderSaini0]

Fixes #132
I add a checkbox state.

+ hidePassword: network.password.length !== 0 && checkbox

this is the main logic used to fix the bug !

How it works

we want to set hidePassword to false when we set encryption from none --> WEP/WPA
for this i check the password length , if it's zero it will suggest we moved from none --> WEP/WPA

but this logic will set hidePassword to true when length is not 0 and we move from WPA --> WEP or other way
hence we also need to add a check if the checkbox is selected or not !

I updated the implementation to use network.hidePassword and also re based with master to resolve conflicts.

Hi @PushpenderSaini0 thanks for the patch! I've checked this out locally and while it does resolve the bug, I think the only necessary changes are line adding the checked attribute and setting hidePassword: false for the None encryption mode.

If you'd remove the changes to line :191 and :202, I'd be happy to merge
