**Short description of error**
When the user assigns a custom shortcut to the Set Key interpolation pop up menu, all interpolations
get the same menu. The expected action is to get an independent shortcut keyboard targeting a specific interpolation method.
Since the bone constraints have different keyboard shortcuts individually assigned, I thought
that key interpolation in the fcurve could have the same individual assignments but it seems not possible
even if I go through the keyboard mapping, there is no way to create an individual custom shortcut for
"linear interpolation".

**Exact steps for others to reproduce the error**
Create a monkey
Open an Fcurve window. Set keyframe on frame #1. Move the monkey (rotate, move) to another place in 3d viewport.
Set another keyframe on frame #10
Select both keyframes, press "T" to get the interpolation pop up menu.
Right click over "LINEAR interpolation", select make new shortcut.
use CTRL+SHIFT+L
All the shortcuts in "Set Key interpolation" will now use CTRL+SHIFT+L

If the user opens Edit->user prefs->keymap->Graph editor->Graph editor (global)-> and creates a new shortcut using: graph.interpolation_type set to Linear, and set the keyboard shortcut, then it gets correctly created.
