Always print with "print-level" and "print-length" nil

This prevents Emacs from inserting "..." in place of very deep or long
data structures, which could corrupt the status file in some cases.
This is done by defining a wrapper function "el-get-print-to-string",
which el-get should use for all "critical" stringification tasks.

As noted in #689.
