emulators: Add caprice32.

Caprice32 is a software emulator of the Amstrad CPC 8bit home computer
series. The emulator faithfully imitates the CPC464, CPC664, and CPC6128
models. By recreating the operations of all hardware components at a
low level, the emulator achieves a high degree of compatibility with
original CPC software. These programs or games can be run unmodified at
real-time or higher speeds, depending on the emulator host environment.

For copyright reasons ROM files cannot be redistributed with the package.

Caprice32 searches ${PREFIX}/share/caprice32/rom for BASIC and AMSDOS ROM
images in MAME/MESS format (only not compressed), e.g. cpc6128.rom and
amsdos.rom.

Note that Caprice32's executable name is "cap32" rather than "caprice32".

The F1 key opens Caprice32's menu.

 The configuration file contains various configuration parameters, some of which can be modified from the GUI.
 When saving the configuration from the GUI, it will be written in the configuration file specified by the \fB\-\-cfg_file\fR switch, if it exists, else in $CWD/cap32.cfg if it exists, otherwise in $HOME/.cap32.cfg.
