Improvements for SearchPlugin

[ZakarFin]

• Make the search plugin larger when it's showing the search field.
• Make it less transparent when the field has focus (so text on map doesn't show through)
• Add options how to show results by channel when there are multiple channels queried.
• Triggers searches for each channel separately so slower channels don't block showing results from faster channels

The question mark icon shows channel description in tooltip when available (mostly for WFS search channels for now).

TODO: for replacing current search on geoportal with this:

• autocomplete when available
• add handling for Search.AddSearchResultActionRequest and Search.RemoveSearchResultActionRequest

Using defaults:

{
    id: 'Oskari.mapframework.bundle.mapmodule.plugin.SearchPlugin',
    config: {
       // allowOptions: true,
       // columns: ['name', 'region', 'type'],
       // useInfobox: true
    }
 }

Single search channel (shown in generic search results accordion)

Multiple search channels (shown as accordions per channel, named after channel)

Using configuration to use infobox instead of marker, selecting columns to show on result table and allowing options to be shown for user

{
    id: 'Oskari.mapframework.bundle.mapmodule.plugin.SearchPlugin',
    config: {
       allowOptions: true,
       columns: ['selected', 'name', 'type'],
       useInfobox: true
    }
 }

Using the theme from Paikkatietoikkuna:

Single channel

Multiple channels
