add search and find functionality

[cdepillabout]

It would be great if Termonad had the ability to search for and find text in the terminal.

Roxterm provides a similar functionality:

If you click Find, you get a dialog asking you what to search for:

The steps for adding this would be something like as below:

1. Create a menu for Find as described in step 1 of add a way to enlarge font with key combination #10.

2. Setup the callbacks for the menu buttons as described in step 2 of add a way to enlarge font with key combination #10.

3. Create a dialog asking the user what to search for. Here is a example of creating a dialog box (but there might be a much better way to do it, using the object builder).

4. Figure out how to actually perform a search within a terminal. You'll probably need some functions from GI.Vte.Objects.Terminal.

5. You'll probably also need to figure out how to implement the Find Next functionality. The current state of the search will probably need to saved somewhere. Ideally this would be managed per terminal, instead of with all terminals at once. (Or maybe not?)

I'm currently working on implementing this.
