Store active filters state when reopen filters

[shady356]

Save filters when reopen the filters modal.

Example: If Kanto and Johto was set as filters, store these values so they are still active when you reopen the filter modal. It should also save the combination of the different categories available. Example of code structure:

activeFilters: {
  generations: ['kanto', 'johto'],
  types: ['fire']
}

Could possibly be saved in a vuex state
