UI: Add new node colors for geometry nodes

During the development of the new nodes in the `geometry-nodes` branch
the color of the new nodes wasn't considered, so all of the nodes ended
up red, the color for "input" nodes. This patch introduces two new
colors, one for "Geometry" and one for "Attributes". There are only two
attribute nodes currently, but the next sprint will add two more,
attribute mix, and sample from texture. The attribute nodes are
conceptually different enough from the nodes that modify the geometry
that they deserve their own color.

Geometry Nodes: support swapping inputs in function nodes

This is the same fix as in rB5ae666c2cc67be0e5ffb897c1ff48fe434d7dbc6.

Geometry Nodes: automatically reconnect when swapping inputs

This makes it easier to swap the inputs to the Join Geometry node.
The behavior is the same as in the Math node.

Geometry Nodes: correct modifier name when creating from node editor

The name should be the same as when the modifier is created in the
modifier tab of the properties editor.

Cleanup: Store "is_active" instead of pointer property in panel type

This is consistent with the way other panel type fields are stored.
