Add feature which allows user to directly copy a selected word into susi and open susi

[djmgit]

Presently there is only one context menu that directly searches a selected word. Although it is a great utility, still user might want to simply automatically copy a selected word into susi input field and then edit and finalise the query. This saves the user from typing large words and also editing the query before asking susi to get answer. For example if there is a word on the page 'neural-networks', user might want to search creator of neural networks, in that case using this feature he/she will be able to copy the word into susi (using context option), susi panel would automatically open and then he/she could type in the remaining query.

I would like to work on this.
