Patch: fix recipients parsing when a recipient list has quotes

[Jose Dapena Paz <jdapena igalia com>]

	Hi,

	This patch fixes the capability to create addresses lists when the
string you part from has quotes.

	For example, this string address should be valid:
	"Dapena Paz, Jose" <jdapena igalia com>

	But this string was converted to two addresses:
	"Dapena Paz
	 Jose " <jdapena igalia com>

	We also remove the quotes in name temporary buffer as they're added in
camel side again. If we don't remove them, the quotes are escaped.

+	* libtinymail-camel/tny-camel-common.c,
+	libtinymail-camel/tny-camel-common-priv.h:
+	(_foreach_email_add_to_inet_addr): now we don't use
+	strtok_r() to split the string to addresses, as we
+	weren't taking into account the quotes. I implemented
+	a new _split_recipients() method that takes quotes
+	into account.
+	(_string_to_camel_inet_addr): now we remove the quotes
+	in the name part of an address, as they are added by
+	camel part automatically.
