Fixed easytags#update() to overcome argument limit

The easytags#update() function in my easytags.vim plug-in previously
used the variable argument list notation `...' but I just found out [the
hard way] that this only supports up to 20 arguments. Therefor I've now
changed easytags#update() to receive a list of zero or more filenames
as its third argument.
