Fix players being skipped in processStringTable (#52)
Fix players being skipped in processStringTable (#52)

Due to an error when porting StatsHelix's demoinfocs, players were
skipped if there was a 'gap' between the string-table entries.

So if the string-table's userdata at index 3 was empty, for example,
players at index 4 and above would be ignored.
