Small enhancement to encdb ui

Shift click type checkbox to un-check others
Search button disables itself if the search would return nothing
When using tabs as criteria, if hyper training is available, only require the specified imperfect IVs for the encounter

enc9: be a little nicer and allow a slight search lag by only considering actual encounterable attempts (passing slot check). Can infrequently obtain a 0-speed shiny Foongus via encDB with a few attempts.
