Gromox 2.38

Fixes:

• oxcical: ignore zero-length PidLidTimeZoneStruct on export rather than failing the operation
• freebusy: process events with recurrence patterns > 510 bytes
• mbop-get-freeubsy: respect the absence of start_time,end_time (-a/-b) parameters
• mapi_lib: support TNEF export of messages without PR_INTERNET_CPID
• email_lib: no longer reject import of time-based recurrent series (RRULE line with UNTIL specifier) with a single occurrence

Enhancements:

• midb: deal with folder changes that occurr during times when midb is not running
• exm2eml: add TNEF file export support

Behavioral changes:

• imap: reject creating extant folder
• midb: change M-COPY from a read-write cycle to server-side copy, thereby preserving mail headers from now on
• midb/imapd: folder names are now treated case-sensitive, just like MAPI did it already
