I updated the mame2010 readme and switched to markdown to enjoy some formatting. This creates an error as reported by @mediamogul here: https://retropie.org.uk/forum/post/133826
I don't know this script well enough to know where mame.ini gets placed by `install_lr-mame2010()` but I'm concerned that it's no longer going to the correct place. It should now be in the folder `libretro saves/mame2010/ini`. I'll pursue that in the forums or via another issue.
In this PR I have also omitted the original mame 0.139 "whatsnew" file which seems out of place. No offense if you reject this change.
* rp_module_menus is no more - instead use rp_module_section with one of
- core (core packages)
- main (main packages - which will be installed by default in the image)
- opt (optional packages)
- exp (experimental packages)
- driver (driver packages)
- config (configuration packages / tools)
* The setup menu organises the data based on the above sections. more could be added in the future if needed. Packages (internally modules), can be added / configured / removed individually, or as entire sections.
* The setup menu will automatically detect if a binary is available to be installed. the nobin flag is no longer needed. modules that install directly from binary via aptInstall or via a prebuilt binary need to use an install_bin_ function instead of install_
* rp_module_section of type "config" will have the "gui_" function called first if it's available, otherwise a standard depends/sources/build/install/configure will be called
* configure is no longer used for "gui" configuration function - use gui_ instead. Had already started to move to this before, but now it is required.
