I propose the following simple patch for src/dsr/model/dsr-option-header.cc

Issue:

I am writing a vanet simulation script, which includes DSR.  I am using config-store to save settings (raw text mode).  When I then try to read in the config file I just saved, I find that these settings fail to parse correctly, because they were written to the raw-text config-store file as quoted strings, which contained spaces.  The config-file read/parse then fails (NS_ASSERT) to re-load these saved settings.  My work-around is to simply replace the spaces with underscores in this attribute.
