Rename or move auxiliary functions

[ssiccha]

The ResClasses package contains auxiliary functions, some of which might be helpful for all users of GAP, e.g. the LogToDatedFile function. I suggest to move those functions that are interesting to all GAP users to the utils package. The utils package is a better place for them IMO.

For those functions that are ResClasses specific, depending on the function you could either

• prefix them with ResClasses so that it is clear, that they are not general functions or
• put them into a file which is not loaded by default or
• remove them from the package and put them into e.g. you .gaprc.
