Fix Name Clashes with Alan Language by Alan Tech. Inc.

[tajmone]

Tweak the Alan syntax definition to avoid any potential conflicts with the Alan programming language by Alan Technologies, Inc (alantech/alan#548).

File Names

In the event of an upcoming package for Alan Tech's Alan lang we should rename all the syntaxes files and their internal names to avoid conflicts in case a user installs both this package and theirs.

• ALAN — Alan.sublime-syntax
  • Rename Syntax to Alan IF.sublime-syntax
    • name: ALan IF
  • Rename all associated ST files and themes accordingly.
• ALAN Solution — Alan Solution.sublime-syntax
  • Rename Syntax to Alan IF Solution.sublime-syntax
    • name: ALan IF Solution
  • Rename all associated ST files and themes accordingly.
• ALAN Transcript — Alan Transcript.sublime-syntax
  • Rename Syntax to Alan IF Transcript.sublime-syntax
    • name: ALan IF Transcript
  • Rename all associated ST files and themes accordingly.

Scopes

Likewise, we should change the base scope name used by this package.

• ALAN → source.alanif
  • Fix all other package files that rely on scope for their functionality:
    • Build files.
    • Color schemes.
    • Comments Preferences.
    • Completions.
    • Indentation rules.
    • Snippets.
    • Symbols.
    • Syntax tests.

The scopes of the other syntaxes are fine, and not at risk of clashing:

• ALAN Solution → source.a3s
• ALAN Transcript → source.a3t
