Creates a new GMimeFilterFrom filter. If mode is
#GMIME_FILTER_FROM_MODE_ARMOR, the from-filter will encode from
lines using the quoted-printable encoding resulting in "=46rom ".
Using the #GMIME_FILTER_FROM_MODE_DEFAULT or
#GMIME_FILTER_FROM_MODE_ESCAPE mode (they are the same), from lines
will be escaped to ">From ".
Note: If you plan on using a from-filter in mode ARMOR, you should
remember to also use a #GMimeFilterBasic filter with an encoding of
#GMIME_CONTENT_ENCODING_QUOTEDPRINTABLE.
