#34 Avoid an implicit memcpy() in event.c

[Pete Batard]

• When copying structs, some compilers (e.g. MSVC for ARM) will use an implicit call to memcpy(), which can result in an undefined reference.
• Use CopyMem() to duplicate struct data instead.

NB: This patch also removes trailing whitespaces in event.c
