Structure tree shows wrong specific tech names

[elexis]

If one opens the tech tree and looks at the name of a tech that has a specific name, change to a civ that has a different (or no) specific name for that tech and then change back, then that tech will display the second civ's specific name (or in the case where the second civ doesn't have one, no specific name at all). F.e. the "Steel Working" upgrade at the blacksmith for iber and maur, or the "Sentries" upgrade belonging to the wooden and stone towers when switching from a hellenic civ to a non-hellenic civ and back again. Bug reported by WarBeast.

Few notes: 1.

if (template.name.specific != template.name.generic)
    return template.name.specific;
else
    return false;

Could be written shorter:

return template.name.specific != template.name.generic ? template.name.specific : false;

2.

if (template.name.specific.generic)
    return template.name.specific.generic;
return false;

The same:

return template.name.specific.generic || false;
