Alias dll names must be specified as lower case

[vbfox]

Description

Contrary to what the documentation specifies library aliases dll names must be lowercase, it mean that the example in the documentation doesn't work.

The correct version being :

PackageA
  alias a1.dll Name2,Name3
  alias a2.dll MyAlias1
Dapper
NUnit

Repro steps

1. Apply what the documentation specifies :

   PackageA
    alias A1.dll Name2,Name3
    alias A2.dll MyAlias1
   Dapper
   NUnit
   

2. Run paket install

Expected behavior

Aliases are created when the exact dll name is specified.

Actual behavior

Doesn't create aliases in the project file.

Known workarounds

Please provide a description of any known workarounds.

Bla bla

Ideally the case would be completely ignored.

Also the current code matches on substrings & that might be a litle bit surprising (alias c foo will alias any dll containing the letter c)

ProjectFile.cs :

                    let l = lib.ToLower()
                    let aliases =
                        aliases
                        |> Seq.tryFind (fun kv -> l.Contains(kv.Key))
                        |> Option.map (fun kv -> kv.Value)

i'll send a PR with a fix
