Add support for relations

Relations are not only to describe a relation between components, but also a way to define absolute positioning of the components.

Following possibilities to create a relation have to work:

node s1 -> node s2  # 1 Position to the right
node s1 --> node s2 # 2 Positions to the right
node s1 <-- node s1 # 2 Positions to the left
node s1 l--> node s1 # 2 Positions to the left
node s1 t--> node s1 # 2 Positions to the top
node s1 u..> node s1 # 2 Positions down, dotted relation
node s1 u  > node s1 # 2 Positions down, no relation is drawn
node s1 l==> node s1 # 2 Positions to the left, with a big relation line

Due to lexing and parsing, nesting the components should be obvious:

node s1 as s
s --> cloud foo as bar {
  actor bla d..> actor blubb
} r   > node s2
