"applet" directory for build targets...

Please, return the possibility to create applet folder like in version 0017. May be in preferences. I see at least two reasons for it:

  1. Sure, that more than 1% of users are with brains and want to keep .hex and .elf files with sketch for future investigations or just using without necessity of every time compiling /uploading to get files again.

  2. In Windows - temp folder like build1755132727304913499.tmp are usually in directory C:\Documents and Settings...\Local Settings\Temp, which is usually hidden. So it is necessary to keep Hidden files opened, which is not very smart idea.
