make history be selectable & copyable

[Former user]

Originally reported on Google Code with ID 324

What steps will reproduce the problem?
1. evaluate expressions to create history
2. try to drag-select numeric value from history display
3. you can't
4. obviously you can't copy a history value either

What is the expected output? What do you see instead?
copy

What version of the product are you using? On what operating system?
0.10.1, macos 10.5.8

Please provide any additional information below.
You can double-click a history item and this inserts its result in the
input window, but that is somewhat tedious since you then have to copy it,
and then delete it again. Plus, it gets inserted at the insertion point
which can mess up the expression you're working on.

``` This is implemented for the upcoming 0.11. The display is text based and allows the

copy of any portion of text, either by drag and drop, or context menu > copy command. ```
