Added expression syntax description to documentation.
Use bulleted lists.
Split bundles of reported signals or connections into multiples of 20 messages to prevent bundle from growing too large.
Add instance-related functions to Windows DLL exports.
Add msig_set_instance_management_callback() to DLL export list.
Renamed MAPPER_TIMETAG_NOW to MAPPER_NOW; also redefined it internally as {0L,1L} to avoid accidental usage - this does not imply anything about immediate dispatch however, since there is no concept of TT_IMMEDIATE in libmapper and all bundles will have real timetags.
Merge remote-tracking branch 'steve/master'
Revision of instance release/release_request logic: devices must pass release messages downstream regardless of whether they are the originating device/instance owner. Release request messages will only be used when sending to instance originator.
If input signal is released locally, send release request upstream but do not release instance.
