Restructure repository to get rid or eb200x directories and file suffixes

This commit modifies the repository in the following ways:
* deletes all files under */eb2007 directories
* renames all files like <X>/eb2008/<Y>_eb2008.<Z> to <X>/<Y>.<Z>
* merges robo{orte,ttypes}_xxx libraries to robo{orte,ttypes}
* Updates Makefile.omk files to the above changes
* Removed Robomon tabs for past years

Reasons for this cleanup are the following:
* Filenames was used for things which can be managed better by SCM
  tools (like GIT).
* The actual code often mixed usage of eb2007 and eb2008 files/libraries
  together. This was probably not intentional, but it could lead to
  very bad mistakes.
* The code for older years was never used in reality and it only made
  maintanance of code harder.
