Adding several pictograms/images at once to a grid

[arasaac-dga]

Add an option to search and add automatically several pictograms or images at the same time to a grid. For example, writing words separated by ";" and search them in ARASAAC's API.

Related: When you use the 'Add multiple grid items' function, it doesn't only fill out the words but automatically searches for and inserts images that are fitting to the word. One then still has to correct any images that don't fit what one wants after all, but it saves some time.
