The Cheats manager should be updated when the ISO is changed because it's non-modal
Removing code that read the ID from file because the cheats manager only has a use when an emulation is running (when the ID doesn't need to be read from the ISO again because it's in a variable). This fixes loading Gecko codes for .wad during an emulation because "VolumeHandler::GetVolume()" return false in this case
The "Download Codes (WiiRD Database)" button is enabled (and its click return silently without an effect) when "Tools → Cheats Manager" is opened when there's a running emulation for which there's no "[Gecko]" ini section, confusing the user about the reason for not downloading codes or showing an error when there's no running emulation
Solution
when there's a running emulation: fix the button
when there's no running emulation: disable the button (to indicate to the user that this button must be clicked elsewhere, in the ISO settings dialog, the user will realise or remember)
autoconfiguration tests. Some versions of gcc care enough about ANSI C
to complain about this.
Use the Linux install hierarchy conventions on other Unices as well.
XKeysymToString returns NULL on unknown keysyms, which is not a valid
std::string initializer.
There appears to be some disagreement regarding the second parameter
to iconv(). Some versions/installations have it as const, others don't.
Unfortunately, due to wonderful C++ brain damage, implicit conversion
from const to non-const doesn't work here.
