Cleanup of Armature 3d drawing.

- In Solid drawmode, bones get drawn solid too now. Including Outline-
selection color, if that's set.
Disable it by setting Object-buttons "drawtype" for the Armature.
Color used for solid bones is in Theme editor.
- EditMode armature now follows (Mesh edit) theme colors (Vertex, Edge)
- PoseMode armature has ThemeColor for selection, and draws three extra
colors now;
- blue shade for bones with action Ipos
- yellow for bones with IK
- green for bones with a constraint
- "X ray" now only works for PoseMode... needs review, can be done better
- "Draw Names" option uses theme color too, also indicates selection.

Fixes;

- In Armature EditMode, the deformed Mesh goes to rest-position
- Border select didn't clear 'active' flag in Bones in PoseMode
- Mouse-click select didn't work when a dashed line was close to Bone
