Core: Add UI option to enable/disable the new zero DOS stub data option.
Unpackers: Add support for new zero DOS stub data option.
API: `DontRealignSections` and `ZeroDosStubData` are now default enabled as this is the general 'correct' way to handle most files. (Some files do require the section alignment to happen and some files may use the DOS stub for self-validation and such. Adjust accordingly when using Steamless.)
This unpacker is currently considered beta. Since I only have 1 sample that uses this variant at the moment, it is not possible to confirm the data and signatures being used are consistent across the board. This variant is also very basic and does not seem to include any means of real protection. (ie. encrypting the code section.) I'd assume this version also did not support x64 files or TLS callbacks so most of the work the other variants can do is left out until other samples prove this needs to support those kinds of features.
