Use NO_OLD_BOTNET by default

[Cizzle]

Might be time to #define NO_OLD_BOTNET in eggdrop.h by default as this is still something from before eggdrop v1.3. Need to precede this by double-checking no old botmessage commands are used anymore (like "error" still is).

Should the NO_OLD_BOTNET macros be removed and thus no longer support linking to pre 1.3.x bots? Or are you suggesting leaving the macros and just changing to #define NO_OLD_BOTNET by default?

Some notes from review:

• Looking over the C_bot[] array, the "away" entry appears to be for old bots (newer bots just use the 'i' (idle) command). However, there are no #ifndef around it (I believe it should be though).
• Some of the code still uses "error" like you have said; it should be converted to using 'e' (which is already an entry in the array; looks like botcmd.c and dcc.c are the only 2 files).
• The "linked" botnet message doesn't appears to only be used for old bots (It doesn't have #ifndef around it on the C_Bot[] array.)
• All the rest of the commands surrounded with #ifndef in the C_bot[] array look like they're taken care of properly.

Hope that helps. Let me know if you would like me to take a stab at implementing it.

I suggest to first add the define in a future version (1.8.4? 1.9?) and then in a following version remove it altogether.

Will probably be easier to do this right with the new console logging modes added.
