added thunderforest tiles
added unsafe DataAccess implementation but we need native byte order stuff as a second step
introduced Little and Big BitUtil. fixes #103. incompatible data layout as of new default is little endianness
Measurement: back to RAM_STORE
minor bug fix in unsafe
disconnect shortcuts only
set default of disconnect to true
revert to disconnecting edges too (not only shortcuts where then the LevelEdgeFilter would be required)
find out max edges per node when optimizing
renamed ensureCapacity to incCapacity and removed unnecessary increase code in GraphStorage
insert new edge at the front; bug fix if filter==null in GraphStorage.EdgeIterable
