[Bug+Patch] error in IMAP mailbox encoding

Hi all,

Balsa has a bug in encoding IMAP mailbox names to modified UTF-7 as defined in RFC 3501, sect. 5.1.3 [1], as 
the '\' (0x5c) is encoded as '\\' which is explicitly prohibited.  To reproduce: activate main() in 
libbalsa/imap/util.c, compile it, and run e.g. (yes, the mailbox name is weird, but it includes all special 
cases from the RFC…)

./util 'ϴä ab c&d+e/f\~ßx'
orig='ϴä ab c&d+e/f\~ßx' mbx='&A,QA5A- ab c&-d+e/f\\~&AN8-x' back='ϴä ab c&d+e/f\\~ßx'
WRONG CONVERSION: --------------------------------^^

The attached patch replaces the hand-coded conversion by utilising g_convert(), and also fixes the bug.  For 

./util 'ϴä ab c&d+e/f\~ßx'
orig='ϴä ab c&d+e/f\~ßx' mbx='&A,QA5A- ab c&-d+e/f\~&AN8-x' back='ϴä ab c&d+e/f\~ßx'
PROPER CONVERSION: -----------------------------^
