Bug #6575	Start up variables mix up underscores and minus chars

Description:
There appears to be some confusion on the subject of underscores and minus characters used to construct some of the Startup variables. 
For example under the setup for Replication on MySQL 4.1.7, the correct values is not recognised and commented out:

  replicate-wild-ignore-table=foo.bartab%  ... is commented out as unrecognised

Entering one rule in MA will be stored incorrectly and looking like:

  replicate_wild_ignore-table=foo.bartab%  ... is not liked by mysqld-nt.

This appears to occur in a number of other places for the various startup vars.

How to repeat:
Use the MA to enter new Startup variables and then check out what has been added to the My.ini file.

Suggested fix:
Only use one or the other character, then WE will not get confused and nor will those doing the programming!  :-)

MySQL server should accept both "-" and "_" in the option names (and MySQL server 4.0 does it).
So I changed Category to "MySQL Server".
Verified with version 4.1.7
