Switch to x64

[numeredev]

DESCRIPTION

Is your change request related to a problem? Please describe. An x86 application is very limited in RAM usage, which creates problems for larger tables.

Describe the solution you'd like Switch everything to a x64 based application. We have to evaluate, whether it is necessary to support the x86 based application in the future.

Describe alternatives you've considered There's no real alternative.

DEVS' SECTION

ANALYSIS

The following things have to be done:

• Get a 64 bit compiler (e.g. TDM-GCC 10.2) and install that
• Compile all necessary libs with the new compiler or use pre-compiled ones, where possible
• Create new targets and use the standard compiler ID for them (simplifies the set up for new members)
• We probably have to link to other static libraries on 64 bit
• Test the whole compilation process
• Bundle the new compiler and upload it
