* Added ipbus_syncreg_v and dependencies to projects/TLU_v1e/firmware/cfg/tlu_1e.dep

* Edited top level ( top_enclustra_tlu_v1e.vhd ) to add extra shutter_veto port in T0_Shutter_Iface_rtl

* Moved counterWithResetPreload_rtl.vhd to counterWithResetPreset_rtl.vhd
* Changed dep file to include new files.
* Minor change to dualSERDES_1to4_rtl.vhd to hopefully remove a warning message

* Adding SyncGeneratorIPBus_rtl.vhd , which is a wrapper to SyncGenerator_rtl.vhd , giving an IPBus interface
* Modifications to SyncGenerator_rtl.vhd to tidy up code

* Created SyncGenerator_rtl.vhd , which generates trigger veto and shutter signals. (needs to be wrapped in IPBus interface)
* Created counter with preload to top bit as well as reset
