Make the bcrypt.c changes portable

This solves all of our problems with 32-bit time_t on 32-bit Windows.
Only had to revert a single occurance in timeStampToStruct() in
src/main.cpp to match the args of localtime().

Invocation:
find src/ -type f | xargs sed -i 's/time_t/int64_t/g'

-## Code guidelines
-
-Alright, you're up to speed on Git and ready to go. Here are a few specific code guidelines to try and follow:
-
-### Match the styling
-
-Pretty straightforward, make sure your code looks similar to the code around it. Match whitespacing, bracket styling, variable naming conventions, etc.
-
-### Prefer short-circuiting
-
-To minimize branching complexity (as this makes the code hard to read), we prefer to keep the number of `if-else` statements as low as possible. One easy way to achieve this is by doing an early return after branching into an `if` block and then writing the code for the other path outside the block entirely. You can find examples of this in practically every source file. Note that in a few select situations, this might actually make your code less elegant, which is why this isn't a strict rule. Lean towards short-circuiting and use your better judgement.
-
-### Follow the include convention
-
-This one matters a lot as it can cause cyclic dependencies and other code-breaking issues.
-
-FOR HEADER FILES (.hpp):
-- everything you use IN THE HEADER must be EXPLICITLY INCLUDED with the exception of things that fall under Core.hpp
-- you may NOT include ANYTHING ELSE
-
-FOR SOURCE FILES (.cpp):
-- you can #include whatever you want as long as the partner header is included first
-- anything that gets included by another include is fair game
-- redundant includes are ok because they'll be harmless AS LONG AS our header files stay lean.
-
-The point of this is NOT to optimize the number of includes used all around or make things more efficient necessarily. it's to improve readability & coherence and make it easier to avoid cyclical issues.
-
-## When in doubt, ask
-
-If you still have questions that were not answered here, feel free to ping a dev in the Discord server or on GitHub.
