`RoughDraft.Media` pseudotype improvements

[StartAutomating]

Get-Media returns RoughDraft.Media objects.

These should be extended so that they may be more useful:

• [ ] #212
• [ ] #220
• [ ] #221
• [ ] #218
• [ ] #216
• [ ] #219
• [ ] #217

Once Media metadata is isolated (#224), we should make many script properties to manipulate common metadata:

• [ ] #226
• [ ] #249
• [ ] #227
• [ ] #228
• [ ] #229
• [ ] #230
• [ ] #231
• [ ] #232
• [ ] #271
• [ ] #233
• [ ] #234
• [ ] #235
• [ ] #236
• [ ] #237
• [ ] #238
• [ ] #239
• [ ] #240
• [ ] #241
• [ ] #242
• [ ] #243
• [ ] #244
• [ ] #245
• [ ] #246
• [ ] #225
• [ ] #247
• [ ] #248
• [ ] #260

Once MediaType classifies media, additional pseudotypes should exist:

• [ ] #213
• [ ] #214
• [ ] #215
