Summary: Generic.pm does unnecessary initialisation

Initial Comment:
Initialisation of generic parser is don in sub read_config. Since it is called only once, it is a good place to proceed with various tests, such as tools version number. This is done with the Perl backtick construct, executing a shell command as an independent process.

Some security rules may forbid such a parallel execution from a web server (e.g. on SourceForge). Thus, initialisation aborts and LXR can't display files. To circumvent the problem, initialisation should detect whether it is call from shell contect (i.e. from genxref) or from web context.

Since there is no need of ctags in web context, this verification should not be attempted.
