Bounty #1 for Homayoun

[kirillt]

We need to solve several issues at once:

1. Migrate ResourceId from crc32 to (crc32, filesize) #20
   Ensure that everywhere ResourceID is taken from arklib, right now it is CRC32 checksum + filesize.
   When we need to print a string with both values, we can just delimit them using dash (-).

   • Update ARK-Shelf
   • Update ARK-Shelf-Desktop
   • Update ARK-Navigator
     We should also implement migration in ARK Navigator, i.e. check some value (or index version) in app data and if there is none (or version is too low) then perform storages upgrade. Index and previews could be just dropped. Storages must be backed up before performing upgrade and old resource ids must be replaced by new resource ids. E.g. 5839051: english, greek must be replaced with 88363-5839051: english, greek in .ark/tags, etc.

2. Provide Android API for indexes and storages #21
   Basically, we just need to take code from Navigator and move it into arklib-android, ensuring any app could just import couple of modules and use metadata as well as index. We don't really need indexing in the apps right now (except Navigator). Could be useful later.

3. Separate user-defined properties into dedicated storage ARK-Memo#8
   We need to use new metadata storage and separate title into it. Also, we can introduce created-date metadata field.
   This issue is kinda similar to Handling Link-to-Web resources using ArkLib ARK-Shelf#21

Just noticed that Navigator writes empty metadata storages to disk:

[kirill@lenovo ~]$ for f in Pictures/.ark/meta/* ; do cat $f ; echo ; done
null
null
null
null
null
null

I think, we should not write empty storages. Not all resource kinds use metadata storage at all, so better to keep disk clean.
