Fix compile warnings
annotations: use OMNeT++ canvas instead of dummy modules (if OMNeT++ 4.5 is installed)
pass information about collisions and channel busy state to upper layers
add possibility to enable/disable collision statistics through PhyLayer80211p ned parameter
add possibility to change cca threshold
new improvements and features for phy and mac layers

improvements include:
1) all possible modulation and coding schemes: now all 11p datarates (from 3 to 27 Mbps) can be used
2) the possibility to attach a control message to a WaveShortMessage to choose MCS and transmit power to be used for packet transmission
3) the possibility to set default tx power and MCS from higher layers

5) the possibility to enable/disable collection of collision statistics via omnetpp.ini
change bitrate type from double to uint64_t
correct case
annotations: fix error when trying to hide non-existant annotations
annotations: fix lines not being drawn
traci: refactor to break into smaller parts and hide internals
hack around the launchd stopping proxying as soon as SUMO exits
let sumo-launchd relay one last piece of data when the sockets start failing
Move all source code under src/veins/ and add --no-deep-includes to Makefile
Change all veins #include directives to use double quotes instead of angle brackets
remove dead code relating to MIXIM_INET
fix typo in method name
phylayer80211p: inform decider about cca threshold changes
traci: add GUI commands to adjust view and take screenshots
