Add log Syntax Highlighting

[ptr1337]

Hi,

wastegun/bin has currently also the syntax option called "log", which is quite useful for debugging and going through logs.
Please consider to add it also here. :)

Hmm, but doesn't such syntax depend on the specific log format? As far as I understood bin took the syntaxes from broot which itself compiled it from the bat syntaxes. But not sure which of those would match "log".
