Add new actor[].flags flag 2048 (SPRITE_NOCLIP), for 'spriteflags' CON usage.

Actors are always moved such that _they_ clip against blocking sprites, even
if their blocking bit is clear. Setting the new bit make them not clip against
anything.  The promary use of this is for decorative moving sprites that are
spawned in masses, such as rain or snow.

engine.c, in engine_addtsprite: if we can't add more tsprites because we
already have MAXSPRITESONSCREEN of them, return 1 to signal that the caller
should break out of the loop.

Tweaks to compile the release build with clang. Now if it only would not
generate curious code like this one (Ubuntu 11.10's clang 2.9 on i386):

   0x080a57ea <+538>:   xor    %al,%al
   0x080a57ec <+540>:   test   %al,%al
   0x080a57ee <+542>:   jnz    0x80a57f2 <initgroupfile+546>
=> 0x080a57f0 <+544>:   jmp    0x80a57f0 <initgroupfile+544>
   0x080a57f2 <+546>:   shl    $0x4,%edi
