Loading time optimization (#1569)

Browse Source 
* On init, rebuild the dictionnary only once

* Fixed first dictionary update to avoid rebuilding multiple times. Commented some very verbose debug logs (should create a new level: UVERBOSE or UTRACE)

* bump version 0.23: added parameters "Mem/LoadVisualLocalFeaturesOnInit", "Mem/FlannIndexSaved", "Kp/SerializeWithChecksum".

* Renamed Mem/FlannIndexSaved to Kp/FlannIndexSaved. Update UI Preferences with new parameters.

* commented some very verbose debug logs

* Warn flann index serialization not implemented on windows

* Warn flann index deserialization not implemented on windows

* Removing some verbose logs

* missing header (win32)

* Added GlobalMap::fullUpdateNeeded() function

* Adding log

* Save flann index even if links changed

* log time to serialize flann index

* Make dictionary modified only after we update
