Use from_scm for numbers
The most commonly used syntax for converting SCM to C++ types is from_scm, and it spares remembering lots of function names. This commit does the search&replace conversions:
scm_to_double → from_scm<double>
scm_to_int → from_scm<int>
With this change and !1542 (merged), few callers of scm_to_*
and scm_from_*
functions remain.
