Summary0005263: CAP subcommands are case sensitive
DescriptionIt appears that CAP subcommands such as LS and REQ are case sensitive as /cap ls gives back invalid subcommand yet /cap LS gives the usual response. This appears to happen for req vs REQ as well thus all commands are likely effected. Tested and confirmed on UnrealIRCd versions 4.0.23 and 4.0.17 though it most likely effects all hat support the CAP command.
Steps To ReproduceRun any CAP subcommand in lowercase and observe the response CAP invalid subcommand
Run any CAP subcommand in UPPERCASE and observe the expected responses/behaviour.
Additional InformationThis likely occurs on all UnrealIRCd versions which implement the CAP command.
TagsNo tags attached.

The CAP specification does not specify if the command should be
case sensitive or case insensitive, only that the capability names
are case sensitive.
Since in the IRC world generally everything is case insensitive,
except modes and who flags come to mind.. and some message tags,
the code was now changed for the command to be case insensitive.

I made a typo in the commit message, of course I mean "Make CAP commands case INsensitive" ;)
