redux store structuring

[ddelpiano]

As discussed over a call with @jrmartin , it would greatly help to slightly change the redux store with a better structure to follow the pattern below:

• add to the current GENERAL_DEFAULT_STATE an object to address all the components of the UI, this will help to store each component global information and keep track of visibility and focus between all the components, an example below

export const GENERAL_DEFAULT_STATE = {
error: undefined,
idsMap: {},
idsList: [],
...
ui: {
termInfo: {
visible: false,
focus: false,
},
canvas: {
visible: false,
focus: false,
},
termContext: {
visible: false,
focus: false,
}
...
}
}

• move each store property component specific into the right context in the ui object, for instance termInfoVisible can be moved in ui.termInfo.visible, circuitQuerySelected can be moved in ui.circuitBrowser.querySelected, etc.
