editor_main: adding missing objects to list

[q8X]

Fixes #601

I think you should've used the model names instead of custom names, just like every other object

FYI in the client objects.xml list for the Object Browser, multiple keywords are available for all weapon models

mtasa-resources/[editor]/editor_gui/client/browser/objects.xml

Line 2457 in 03c0861

<object model="346" name="Pistol" keywords="weapon,22,colt-45" />

The names from getObjectNameFromModel which this PR modifies (it's serverside) are only used in serverside function assignID which the map editor calls when assigning a new name to an element placed using the Map Editor.

So this PR is fine tbh, the names used for weapons are more descriptive than their DFF names.

i used engineGetModelNameFromID to get the names of the missing objects, feel free to make PR to change these if u want
