DGT-OmegaT : new versions published

All these changes concern only the normal search in project screen, neither search on directory nor replace nor pre-translate.

Orphans are now separate search domain

In previous release, orphan segments had been re-integrated as a part of "Memory", including ongoing segments. Now we make distinction between ongoing (segments which are translated in project_save.tmx but also present in source documents) and orphans (segments translated in project_save.tmx but not anymore present in the source documents)

Search in segment properties

Previously the text search zone contained three fields for search in source, translation and notes. Now the third field is a selection between note and properties: you can use it to search in the <prop> values of a segment coming from TMX.

Properties are converted to a long string with one property per line, each one in the form "key: value" (with : and a space). Note is also included, so this mode means in reality note + properties.

For ongoing and source segment, actually properties are id and path from the key, if exists. We do not yet support the free fields in source documents as in OmegaT 4, but it is an eventuality for the future.
