allow sexps which reference sounds to use either the table index or the entry name as the reference (based on a patch by m!m, see http://www.hard-light.net/forums/index.php?topic=86293.0)

I forget who requested this, but this change now causes FRED to allow numeric sexps to be used for OPF_WEAPON_BANK_NUMBER

related to Mantis #3121, add parentheses if the string passed to runSEXP doesn't have them

git-svn-id: svn://svn.icculus.org/fs2open/trunk/fs2_open@11110 387891d4-d844-0410-90c0-e4c51a9137d3

Wrong variable type, may work in MSVC but not on clang or gcc.

better method of appending ellipsis (nb: strncpy pads with 0 if string is shorter than len)

technically, this is better

git-svn-id: svn://svn.icculus.org/fs2open/trunk/fs2_open@11115 387891d4-d844-0410-90c0-e4c51a9137d3
